I have a trio of dutch bantam x's, a hen, and rooster pair and then their baby which is a hen and she's about 3.5months old. The momma hen (Roxy) lays almost every day for me and I noticed when she is laying the rooster and baby hen each get in their own nesting boxes and sit while she sits. Is this normal? They don't do it any other time just when the laying hen is laying. There are other chickens in the coop, they actually sort off into thier own breeds. There are 2 cochins that stick together and 3 silkies that stick together. So basically there are 3 flocks living together. When they free range they each go in their separate groups by breed. Just wondering if I'm the only one with wierd, yet pretty smart chickens.
