I have a 5 week old RIR from my local co-op. All has been well but she has shown signs of falling behind the others in size. She behaves usual as far as I can tell. She does act crazy hungry when I feed them. I have noticed the largest Buff has begun dominating her when she tries to eat. This morning I notice one eye is red and irritated. I have also been keeping an eye around the sides of her neck where she really has no feathers. Running parallel to her neck length. Sounds like some wetness from her nasal area this a.m. also. It has been unusually cold here in TN for the past few days though. Hopefully these pics are well enough.
