My almost 5-week-olds have been outside for the past week. Our temps have taken a plunge the last day or two, so I put in an extra heat source. I have two in there now. They have a brooder/warmer area that stays really warm, it was 72 on the outskirts of the heat this morning, and probably near 85 or more right under the heat. The brooder/warmer area is about 4x2ft and they can go there any time (and do). But...the high today is only supposed to be 47, and the lows tonight in the mid 20s. That's so cold!!! Their coop is draft free and actually gets pretty nice and warm because the sun comes through the windows, but it probably won't be much warmer than 60 in there at these temps (except for the warmer area, of course). Will they be OK like this until the cold spell snaps? They have a doggie door and can go outside if they want. They were out yesterday and it was about 45-50. Just went out, played, went back in, warmed up, rinse, repeat, lol. I hate to bring them back in at this point. They are getting really big and are used to all the freedom. There are six out there in a 8x8 coop and a 192 sq. ft. run. They have a really good time, but I will bring them in if it's better for them. What do you all think?
