Hello all, I'm sure this question has been asked before, but I don't have time at the moment to search the threads . . . Our broody mama just hatched out some chicks today and she is doing a great job keeping them warm under her, but I'm wondering if I need to add a heat lamp in the coop too? It's chilly here and supposed to get down to 35 F tonight. This is our first successful hatch, so we are newbies, and being at this time of year I was just a little concerned about keeping them warm enough. Thanks! ~Carrie ETA: The hen and chicks are in a very small coop by themselves, separate from our other chickens.
