Are you planning cross-breeding Silkies with that Roo in the pen? You want cross-breeds? If you want sweet birds it takes handling them preferably sitting down or crouching and using treats. I have two Silkie hens and they take turns being peckish with each other or with other chickens. Practice handling/picking them up in the judge's hold - takes a little time for chicken and human to get accustomed to it. And, yes, all chickens like soft, turned-over, fine dirt, for dust-bathing.
These are my partridge silkies that I have had for about a month. I was told they are 6 months old hens. I love them, they are so soft!, but I have a couple questions if you guys can help me. The bigger lighter colored one is a jerky lol She picks on the smaller one and when I go to sit with them she like tries to fight me. She walks by me and I pet her and she'll puff up her chest and stretch her neck and peck at me. I gently push her back her up some\ and laugh. It cracks me up but I was wondering if there is away to make her nicer. Also, they have some feathers that like stick together/dirty I was wondering if I should put some loose dirt in there for them so they can dirt bathe??? or if there's some other way.
