I have 9 three to four week old chicks. Feathering very nicely. I am in the Pacific NW... temps at night with a low of 30 degrees. Day time around 45. Can I move these guys outside without a heat lamp? They have a stall coop so they are still indoors, just without a heater running in the area. Our house is usually around 65-70 I am very against a heatlamp in the barn... too many barn fires for my liking. They are getting too big for their brooder...I am starting to feel like a bad chick mom. I have no other chickens. Not to mention they smell and make a mess. I turn the heat lamp off most of the day in the house. It is fairly high up when it is on.
