My five week old Ameraucanas are not happy in the big brooder in my living room any longer, since I gave them a couple days outside last week for about four or five hours each day. So, I have put them out in the tractor today and they are very contented. But, it is going to get down in the fifties tonight and possibly a brief rain shower in the morning before it becomes a nice day. They are all feathered out, I have an enclosure in the tractor and was going to cover all sides for overnight. Do you think they will be okay? When I brought them in last week, they loudly chirped for hours and have been doing it off and on each of the days when they are inside. For my own sanity, I was thinking I would keep them out there.
