My 9 silkies are 9 weeks old and more than ready to go outside but I still worry about them. I put them out today into the silkie coop with my two older silkies (I think maybe both boys). These two older silkies have been so sweet and gentle to the new babies and they are all peeping around together like they have all always been together. Now for everyone to have a nice cozy first night together. They do have a little heat lamp out in the coop for them as well so with 11 chickens piled up I am sure they will all be warm and safe.
