I have 1 chick that is 6wks.old and the other gang of 32 are 2wks.old.I put them out in the barn yesterday for about 2hrs watching them they all seemed to do ok together.Just alittle bumping by the little ones who actually would run up to the big chick stand real tall look her in the eye and starting the chest bumping.Now today they are out there together and the little lite colored chicks who seem more aggressive ran up to the big one and started it again she moved back out of the way then the little one pecked the big one on the neck and hung on the big one chirped real loud then did the same thing to the little one who then ran off.I think they are just establishing their order do you think?
