My chicks are a month old now and have most of their feathers. They outgrew their brooder in short order and the only place I could put them was in my 6' diameter garden tub in the master bath. They are flying out of that now! I live near Brooksville, Fl in the West Central part of the state. The Weather Channel says it will be in the upper 50's at night here for a while. The coop outside is weather-tight and I have a really thick layer of wood shavings in there. Would it be alright to move them outside now? This is my first experience raising chickens. I have 10 pullets- 6 Buff Orpingtons, 2 Rhode Island Reds, and 2 Americaunas. I notched the temp down by steps since I've had them and now the heat lamp is off. There's no electricity in the coop presently, but I can run an extension cord out there if necessary. Any advice for this newbie?
