Can anyone tell me what breed of chicken this might be? We found her wandering around campus lost, pale, and dehydrated (we're in TX and it's over 100 daily right now). We tried to find an owner but couldn't, so we've got her separated at the moment and will add her to our flock of RIRs once we're sure she's not harboring any illnesses. She's not laying yet (I say she, I'm 99% sure this is a hen, no spurs and very docile), and is very sweet. Also, could anyone take a guess at her approximate age? I'd guess around 5-6 months?
