i just noticed today that one of my hens has diarrhea! i didnt see it yesterday. its like this happened over night! she was roosting when i went in the coop and i looked at her and the next thing i see is her pooing everywhere! it wasnt like a normal poop drop. it was a little almost continuous line... we just switched feed and idk what feed the old owner gave them. and we gave them the feed the guineas ate. and we just switched again (because it was starter feed). the new feed has a lot of stuff in there cant remember what its called. and we also just gave them oyster shells. can yall help! i dont want to loose a hen!
