Old aged lead hen, hasn't really laid eggs much for last couple years. Has been staying in the coop the last couple days. Looks normal, comb looks okay. Poop, maybe a little watery. She seems like she's mispecking some at food, but does land some pecks. I don't think she's that hungry, but tries to be "normal" so she doesn't get bullied, plus she's proud. I gave fenbenzanole 2 days ago. Please advise, I believe it's a health issue, not an emotional one. Thanks
