My Silkie hen, who is 11 months old, went broody last month. I had been collecting eggs to put into our homemade incubator, so after a couple of days, when I was pretty sure she was serious about staying on the two eggs she had in her nest, I put six more of her own eggs under her. She has been a great mother, taking super care of the eggs and last week hatched 6 cute little Silkie chicks (two of the eggs showed no development when I candled). Just keep an eye on your hen and you'll know when she's gone broody. I've always heard that Silkies make great mother hens.
