I rescued some hens four months ago from a very bad place and one of them was always bad off. She was doing her thing and seemed to be healing but, is now really bad. I know that I need to put her out of her misery but, dont know how. This was never an illness just injuries. Could anyone please tell me the best way to deal with this. I have never had to and dont think my dog vet will be of any help here. Thanks for any help we can get.
