Hi all, I bought 25 baby chicks about 2 weeks ago. Here in Indiana the winter has just started, so by the time these guys and gals are big enough to go outside it will be the middle of the winter. Half are RIR's and half are light brahma's. I know the brahma's are more cold hardy. But I wanted to get the opinion of a few people with more experience than me, as this is my first shot at raise baby chicks. If I put them out from the heat lamps in my garage to free ranging outside in the dead of the winter, is that a recipe for disaster or do you think they could tough it out and make it through?
