In St Peters, Missouri, I have 16 (5) week old chicks in a spare bedroom, I purchased a coop from Rural King 2 weeks ago and put it up in a bedroom due to being too cold for the chicks to be outside. When will I be able to put them in the coop? My coop is built around the outer part of a detatched garage, and there is a 12x12 room in the coop that I can block off so the birds can not go into the other sides of the coop, I was wondering if keeping the 2 heat lamps on would be enough to keep them warm... they are used to the temp being around 65-70 degrees in the house, but our nights are in the low 20's and I worry they may get too cold.
