Hi! I'm new to BYC and have only had chickens for a year. I hatched some of my own Americauna eggs in my classroom about a month ago. They have been living in my bathroom, like their parents did for the first five weeks and to keep them safe from my flock of 11--10 hens and one rooster--I put them in an extra large dog crate in the coop today so they can get acquainted. My question is to prevent a fire can I just cover the crate with a blanket at night until they adjust to the temps? It is in the high 70's and low 80's during the day and low 60's at night here in SW Missouri. I have a thick layer of straw on the bottom of the crate. Thank you for your help!
