I know I got my 2 silkie hens last april, they were about 9 months old and last year they each went broody 3 times each, now they have both been broody already this year. So 4 times each in less then a year. Thats pretty good, I think! I love my silkies, I only put 7 or 8 regular size eggs under each, cause I dont want there to be too many and have some accidently shoved out of the nest. Hopefully if you move her with some eggs, the other hens will stay with their routine on the regular nest boxes and leave her alone. I have one hen on eggs in the regular coop, not locked in. She runs out and eats, poops, pecks at the other birds and runs back in to her eggs, only one other silkie laying right now, and one in the garage with 8 orpington chicks she hatched out for me. It was a hassle having her in the garage but it was really bad weather when she started setting and my daughter was afraid she would leave her nest and since I had bought the eggs, I wanted her to sit tight. She has a few choc orps and lemon orps and the other hen is sitting on lemon orp eggs now. Oh what fun, can hardly wait to see if I got boys or girls....
