We are planning to make a home for our chicks in an empty stall. Will enclose it to keep everything else out. We are in New England, still cold. The chicks are currently in an unheated building but in a dog crate with a heat lamp. I'd like to move them soon, as it's getting crowded and would make them more comfortable and easier to care for. Question: At what age, if I use a heat lamp, could I put them in the barn? And would a 250 watt lamp in one part of the stall be enough to keep 25 chicks warm, or would there be too much area that would be too cold. We are thinking of making a temporary lowered ceiling of pink foamboard, about three feet high, putting the light through that, and building some low roosts around the perimeter. We can also line the stall with loose hay for them to retreat to. We would have shavings on the floor. Would like feedback from those who have moved chicks into a more rugged situation like this at a young age, e.g., one to two months. Thanks.
