Tilting feeder

1. An animal feeder comprising:

a reservoir containing a feed solution for animals;

a dispenser connected to the reservoir, wherein the dispenser dispenses feed solution from the reservoir through an opening in the dispenser;

the reservoir further comprises one or more venting holes to allow the exchange of air with the environment outside the reservoir, wherein the venting holes are positioned above the level of feed solution in the reservoir when the animal feeder is in use;

wherein the opening in the dispensing member is positioned above the level of the feed solution, when the animal feeder is in use;

wherein, when the animal feeder is in use, the reservoir rotates in at least a first plane from at least a first position to a second position to tilt the reservoir in response to changes in the amount of feed solution in the reservoir, and wherein the rotation from the first position to the second position maintains the opening in the dispensing member above the level of the feed solution; and

wherein the dispensing member comprises a mouth leading into the reservoir to allow feed solution to flow into the dispenser as the reservoir rotates.

2. The animal feeder of claim 1 , wherein the dispensing member comprises a channel between the opening in the dispensing member and the mouth for the flow of feed solution from the reservoir to the opening, and wherein, during at least a portion of the time that the animal feeder is in use, the mouth is positioned at or below the level of the feed solution.

3. The animal feeder of claim 2 further comprising a hanger for suspending the reservoir from a hanging member, wherein suspending the reservoir from a hanging member positions the reservoir in at least the first position for use of the animal feeder.

4. The animal feeder of claim 3 , further comprising:

wherein the reservoir rotates in at least the first plane about a pivot, wherein the pivot comprises an aperture in the hanger, and wherein the hanging member couples to the aperture; and

wherein the coupling between the aperture and the hanging member is configured to allow rotation of the reservoir about the pivot and stabilization of the reservoir in at least the second position from the first position.

5. The animal feeder of claim 4 , wherein the hanger comprises a tab configured to receive the hanging member at a first end and connect to the reservoir at a second end.

6. The animal feeder of claim 5 , wherein straps extend around at least a portion of the reservoir to secure the hanger to the reservoir and support the reservoir in suspension.

7. The animal feeder of claim 4 , wherein the tab of the hanger comprises a substantially flat strap having an edge portion, and wherein the edge portion is substantially aligned with the first plane of rotation of the reservoir.

8. An animal feeder comprising:

a means for containing a feed solution for animals;

a means for dispensing feed solution from the containing means, wherein the dispensing means is connected to the containing means; and

a means for rotating the reservoir in at least a first plane in response to changes in the amount of feed solution in the reservoir.

9. The animal feeder of claim 8 , further comprising:

a means for exchanging air in the reservoir with the environment outside the reservoir.

10. The animal feeder of claim 8 , further comprising:

wherein the dispensing means comprises a means for accessing the feed solution by an animal;

wherein the accessing means is positioned above the level of the feed solution;

wherein the containing means the feed solution rotates from at least a first position to a second position to tilt the containing means in response to changing in the amount of feed solution in the containing means; and

wherein the rotation of the containing means from the first position to the second position maintains the accessing means of the dispensing means above the level of the feed solution in the containing means.

11. A method for dispensing a feed solution to animals comprising:

providing a reservoir containing a feed solution for animals, wherein a dispenser connects to the reservoir for dispensing the feed solution from the reservoir to an animal through a first opening in the dispenser and wherein the feed solution in the reservoir flows into the dispenser through a second opening in the dispenser; and

coupling a hanger along an outer surface of the reservoir, wherein the hanger is configured to balance the reservoir in at least a first orientation that positions the opening in the dispenser above the level feed solution in the reservoir.

12. The method of claim 11 further comprising:

wherein the hanger has a length configured to provide a range of orientations of the reservoir, the range of orientations corresponding to the level fullness of the reservoir, and wherein each orientation within the range maintains the opening in the dispensing member above the level of the feed solution.

13. The method of claim 12 further comprising:

rotating the reservoir about a pivot from at least a first plane from at least a first orientation to a second orientation, within the range, to tilt the reservoir in response to changes in the fullness of the reservoir.

14. The method of claim 13 , further comprising:

venting the reservoir, provided by venting holes in the reservoir, to allow the exchange of air in the reservoir with the outside environment.
