Just wanted to share my experience with you all. I have a NN hen that hurt her leg not to long ago. She has been isolated in a large dog crate at night and free ranging right outside her crate during the day. She is "parked" right next to the main coop--- but honestly, they REALLY dont like her. They beat the C*&P out of her whenever they get the chance, so she has been super happy where she is getting special treatment. She is a very docile, nice hen. I was also hatching NN eggs, only three had made it to day 21, two hatched and one was very weak from the day it hatched. It had trouble absorbing the yolk and never got strong- I lost it about a week ago. So I found myself with a lonely NN chick and a semi lonely NN hen. Since she was so docile, I decided to try putting the chick with the hen. She was never brody but I figured I would give it a supervised go ahead. Well, one week later, they couldnt be happier. She lets the chick crawl all over and under her. It sleeps under her at night. She doesnt do the specialized chirps I have heard other mommas do to talk with their babies, but she takes very good care of it, as if it is her own--even though she was never brody or sitting. A happy adoption.
