Yesterday morning I noticed one of my d'Uccle bantams standing on the roost by the nest box.She had her head tucked in and was all fluffed out, typical ''I'm not feeling well'' posture. She drank a little, but was not really interested in eating. Her poop was small and greenish. This morning she wasn't improved, but she ate and drank quite a bit. I'm thinking maybe an egg laying related problem? Any suggestions? I really don't want to lose her! Thanks in advance!
