I have a flock of about 25 in the main house with a private run and they free range about 2 days a week. I have 25 chicks in the garage that are about 9 weeks old. I have an old goat house next to the chicken house that I converted to a new chicken house. Is it ok to go ahead and move the 9 week olds out to the goat pen and close up the door between the two runs so the babies have more room to move around and be outside?? I guess my biggest concern would be predictors since the big chickens wouldn't be able to get to the little chickens. It will also cut the big chickens run in half until I decide it's ok to open up both runs and houses to all the chickens. I think I've answered my own question as the babies will be much happier with all that extra room. Just wanted some feedback!!
