Buenos Dias Arizona Peeps. My chicks (Australorp) are at 6 weeks and getting too big for our brooder setup. I'd like to move them to the coop but these recent temps have me worried they won't be able to take it. Not just the hot temps but also the 30 degree swings from day to night. Am I over thinking this? I've already got some 2 liters ready in the freezer. Any guidance would be super awesome. TY!
