MY girls are 14 months old and they've always been healthy. Last Saturday morning Olive didn't want to leave the roost and that night died in my arms. The next morning Henrietta was acting the same, I picked her up and she threw up. Emergency Google search said sour crop. Since Saturday I've got everyone looking and feeling mostly better with prebiotic, yogurt, vomiting, syringe feeding, etc.. Slight crop impaction in a few in the am and occasional sour crop since then which I am closely monitoring/treating. Comb color improving but they are still somewhat pale and blotchy.. Could it be worms causing all of this? I've never deformed, didn't know I should. I've had trouble with shelless eggs for a few months but couldn't figure out why since they get oyster shells. Production had been down from 12 to 10ish but otherwise they seemed happy, etc. Then diarrhea and Saturday we lost Olive. Diarrhea resolved now but down to 2 eggs a day. They feel lots better but are still sick. They did get a dose of antibiotics. Should I deworm or is something else causing my poor girls all this trouble? Any help would be appreciated! Thanks so much!
