My silkie babies are now 8 weeks old and have grown very big. I was just wondering if I could introduce them to the flock yet? I only have 5 girls in my flock so no roosters yet. They have been quite gentle in their "pecking order pecking" of the new girl I added a few weeks ago, they don't attack. Is it ok to add mama and her babies yet, the brooder is getting small! Thank you.
