I have 6, 5 week old chicks right now. They are inside my house but are getting to big for my brooder. I have an empty rabbit hutch outside that will fit them perfectly right now..but im in NY and it is in the 20's at night..i dont use extra heat for my chickens during the winter, mainly because i dont have electric in the coop and im not running an extension cord. The chickens have always been fine without. What age for chicks is ok to be put outside in winter? I plan on keeping them indoors for another couple weeks..im just worried its to cold out now for them..im scared that if i put them in the rabbit hutch with a lamp itll catch fire... I should of thought about this before i hatched eggs in winter for the first time! But my excitment got the best of me!
