My Silkie didn't growl or peck at me. Granted she is my friendliest chicken and is more like a pet than any of the others.
For me, I went into the coop and noticed she was huddled in the corner on the floor of the coop. I went over to check on her and realized that she was sitting on 10 eggs (only 3 were silkie eggs the rest were a mix from my flock). I'm still wondering how she got the large chickens eggs since the nest boxes are up higher. Anyway, she let me pick her up and move the eggs into a cardboard box. I tried moving her into a separate coop but she wouldn't get back on the nest until I moved her back in with her friends. That was about 19 days ago. On Sunday I moved her into a dog kennel in my bathroom and I am proud to say that she stayed on her nest and that 5 of those 10 eggs have hatched so far.
I'm not sure when she had actually started sitting on the eggs since my husband had chicken chores for the 3 days prior.
