I have 5 hens and 2 bantams (all one year old). I am looking to move my 8-5 week old pullets and 4 bantam pullets outside to the chicken yard. I have a 2 options. My husband build a bantam coop that currently noone is living in that I can move everyone into OR I can put the bantams in the bantam coop and the others in the main coop. If needed I can divide part of the main coop. The pullets are about the same size as my full grown bantams. I didn't know if it is best to divide them now since eventually the pullets won't fit thru the bantam door, or if I should keep the youngens together and in there own time they will move into the main coop.
