Yall may remember my laying issues with my hens or the lack of I should say. I changed their food a couple weeks ago and one of them just started laying beautiful solid eggs and has done so for the last 3 days. Well today, she is acting totally off, lethargic, just stands around with her head tucked in like she does on the perch, she doesnt move or startle when we come near her and just let's us pick her up and doesnt seem to care. She won't take her favorite treat from my hand, black oil sunflower seeds. She is drinking water. I've since felt her crop and it feels very full. Ive been rubbing it gently and she seems to like that but it doesnt seem to help. What do I do, and what could be wrong with her?? Please help, she is my favorite and has such personality, that's why it's so odd to see her this way.
