I put 3 ee in with the 6 older pullets about 10 days ago but they still don't seem to be mingling at all. The 3 just sit on the roost all day until I kick them out of the house to do the feeding and cleaning and stuff and even then they huddle in a corner away from the bigger ones. I have 3 more that I am wanting to put in the big henhouse so that with winter coming I can consolidate the heating of it to just one place. Does/Did anyone have this same problem? I really don't know what to do anymore.
