Sir Crows A lot
I know that when we have them in the house they do chirp and when we walk by they run around so they may be fine. When you do introduce the to the other silkie, make sure the it not mean to them . I have one hen that I can't mix chicks with her because she'll kill them. May help to put them in a dog crate inside the crate so they can see but not touch for a few weeks.
