Hello, I am sure this question has been answered on here before but I can't seem to find it. I have some chicks that were born 2/20 so they are not quite a month old yet, but they are getting big and stinky and I would like to move them outside pretty soon. my problem is I live in NH and it is still freezing during the day here, so obviously much colder at night. I can give them a heat lamp or a brinsea chick brooder (thingie whatever they are called) and close their coop up at night but will it still be too cold? i have a terrible fear of waking up to little chicks-icicles below is a pic of the coop they will be temporarily using until they are big enough for the big coop. It is 4x4. the one on the left- as you can see it closes up all the way so it will stay warmer than something with a lot of openings. thanks for the advice.
