We adopted our first chickens 9 beautiful big girls last summer. they’re all about 2-3 yrs old. This March we got 6 bantam chicks. 2 of them are Roos. We’ve had them separated this whole time but for the last about 2-3 months they free run together but are still sleeping separate. They seem to get along fine but the “little crew” still gives the “big girls” plenty off space and even runs from them if one the big girls get too close. Should they all be sleeping together by now or should I take the “littles” behavior to mean they’re scare of the big girls and for good reason? Or is it just basic respect of the older bigger girls? Such a newbie mistake to mix different sizes? .
