I have been putting the four housebirds outside during the day and bringing them in at night due to low temps. Tonight will be warmer. I am going to put them into a pet carrier and put them into the coop. The pet carrier will keep them close together for warmth and will keep the big mean chickens from hurting them. Do you think I should keep them in the coop for a couple of days and carrier at night before I let them run with the big birds? They are six weeks old. Or should I keep putting them in their own little pen during the days for a while? Their pen is in the yard so everyone has been seeing each other for a couple or three days now. They seem to love being outside....I don't blame them.
