hello all! I’m from Illinois where winters get pretty cold. However, I have successfully merged isa Browns (full size) and silkies (bantams)! They cuddle together in the coop, they lay together in the same spot, and roam the yard together during the day for fun. The full size keep the silkie warm at night, and the silkie roosts actually more then the isa Browns. They are all females with no males on our property. I’ve read COUNTLESS posts about how this can’t happen, the big ones pick on the little ones, etc. IT IS POSSIBLE. We have 4 full size and 2 bantam. They can live together with no problems. I waited a year to post this to watch their behavior but we have never had any issues between the too sizes. I wish more people integrated their flocks. Have questions? Shoot me a message/comment.
