My BR hen has been sittng on a clutch for about a week. I actually have two hens sitting in the same building. One is a mutt bronze BR mix the other my BR hen. I have seen the mutt off her nest every morning for a little bit to eat and drink but have not seen the other hen out at all. Today I spent a lot of time outside and never did see her move. My question: is this normal behavior? She seems alert and quite agressive - hissing when you get close, so I assume she is staying healthy. I just can't believe she has not been out to drink.
