Tonight we put the 8 week olds in the coop to sleep with the big one year old girls. There was a scuffle at first...but with some soft talk, petting and a board between them they have calmed down I keep going out to check on them (worried mother hen). Hope this works out. I think the only reason there was a scuffle was because the little girls were in the big girls spot. I moved them and that helped. Keep your fingers crossed for the peeps please. They have been spending days together...and I want this a all time thing.
