Do you at least have a brooder for temporary housing/warming? We just got our flock of 15, and I built a brooder, very cheaply, at 4x4' just to make sure we had enough room. Needless to say, I could safely put several more in there and they'd be comfortable even at 4 weeks of age.
I bought my materials from Lowe's for a grand total of $85 - that includes all the plywood, 1x1" corner support, the screws, dowels for roosts, the pine shaving bedding, and the lamp fixture. I had to spend an extra little bit at Southern States for the bulb (Lowe's was out) and the feeder and waterer, but all in all, it cost right around $110 in total - and we can easily reuse it for future hatches.
