Boy was Kathy ever right to make sure your sick bird is well hydrated! I had been tube feeding my hen fluids and dilute food during her convalescence from enteritis, but not enough fluids. She hadn't been pooping much and when I investigated I thought she had a stuck egg. Nope, concretions. I am soaking her in warm water with creme rinse (to make it slippery), giving her more fluids orally, irrigating the impaction and picking away at it. I think I'll give her some aspirin (5 tablets dissolved in 1 gal H20 - I think that's right) to take the edge off. She is not very happy about her constipation and having to play anhinga (a bird that swims half-way submerged). Anyone have any other ideas. Do they have lithotripsy for chickens? Wish us luck.
