I believe you raise birds for meat, so have slaughtered before, so will ask:I used flubenvent to worm. Yes poop was bright green and watery. That was Fuglys and one hen. The rest seemed to have ok poops but very reduced and they'd lost weight. I even brought 2 of the hens inside to weigh them compared to last month just to be sure.
Did you open them up to take a look?
