Hi, I have two five month old bantam silkie hens. We also have two bantam silkie roosters of the same age. They all live with the other normal sized chickens who are 6 months old and laying. Does anyone know what age is normal for a silkie bantam to start laying? Are there any signs to look for? And also, my rooster keeps making little nest-type things on the floor and sits there like he's about to lay an egg.. Why?
