Okay so my 1/2 silkie hen, Tabitha, will be 1 in April. She just recently started sitting on 3 eggs for her very first time. I have 10 of her chicks that I incubated and hatched at my house and they are a few weeks old. I thought I would take her and introduce her to them today to see what she did. When I picked her up, I realized that her crawl and her belly were completely bald. She has no feathers on them. Her skin looks perfectly healthy though. What caused this, none of my other chickens have it, just her. Also, she pecked at the chicks. Is this normal?
