I have six ISA Browns and two olive eggers that are just about six weeks old. Tonight when I changed their water I noticed a small ball of what looked like wet food. It was about the size of a peach pit, maybe smaller and smelled pretty bad. It reminded me of what hawks regurgitate after ingesting too much fur or feathers from their meal. From what I’ve read chickens can’t regurgitate on their own. I didn’t actually see any of them produce the little ball but I don’t know where else it would have come from or how it would have ended up in their water. Could one of them have emptied their own crop if it was too full due to sour crop? Any suggestions on what I can do for them if one is ill?
