One of my hens seems to have a very slight cough only very occasionly and her poo seems to be foamy and yellow, AND IT ABSOLUTELY STINKS!! Anyone got any ideas? Thanks!
Cecal poop is the worst! Stinks to high heaven, but is considered normal. Foamy, however, is not. Have you checked for worms lately?
Vaccines are not wormers. You can have a fecal test done by your local vet for a small fee. It is worth it for the peace of mind.
