My fourteen babies are doing just fine in their brooder at three days old. I used my trusty dremel to cut the sides off of two 20 gallon-ish plastic totes, then used the pieces of cut plastic to sheathe the cut ends. I ended up with an enclosure that measures 32”x34”. I then built a square frame with 1x2s and hardware cloth to put on top for A Very Curious Cat (TM) The girls love their enclosure. I have a Brinsea 50 in there with them because I didn’t trust that the 20 would be big enough. It takes up half of the brooder, but they do jump on top and poop/peck at poop/jump off to practice flying /perform sneak pecking attacks. So...I live in NH. We just had two blizzards in a week, and a third is coming in four days. There are good odds that it might be too chilly for outdoor baby chicks at night in eight weeks. What size enclosure should I be planning for if it’s still cold mid-May? I may have to put them in the unheated garage. I’m just wondering what size I should be planning for, and when. Anyone who has had a similar situation?
