My golden wyandotte has been extremely lethargic today--cowering in the corner of the coop or the run. Very uncharacteristic behavior. She's nearly 3 years old. I've been watching her with concern. As she moved out of the coop to the run, another chicken (a Welsummer) pecked her hard on top of her head, drawing a tiny bit of blood at the back of her comb. The Wyandotte ran into the corner and the others are now leaving her alone (3 in flock). Should I pull her out of the coop until she's feeling better (IF she'll ever feel better). Just let them work it out? Given her behavior, I fear she's sick and may be on her last days.
