I have a 3 week old batch of LF chicks in the house in a large tote. When would they be ok to move out into the garage into a brooder? The garage is not heated but I'm going to put a red 250W brooder bulb in as well. I have another batch that is suppose to hatch on Sat. and need the tote for them. The weather here has been 50-60 or higher during the day and at night gets down to the low 30's. Any help would be appreciated!
