Thank you everyone, for the warm welcome! I put golfballs in their nest box yesterday (just to help them know where to put them) and all 3 laid in the nest today (only 3 are laying -- one of the leghorns isn't laying yet)
Chickenmaven - I'm not Silkie crazy yet..... give me some time and I'm sure I'll want one of everything!
Hillbilly Hen - Thanks for the direction, I'll check it out!!
