I have 2 Khaki Campbells about 5 to 6 wks old. they have been inside without a heat lamp for 2 wks. They are getting stinky even though I clean them out with all knew bedding etc. every day. sometimes 2x. I have a barn that I plan to section off for them to stay in at night but temps go down to the mid forties so don't know if the barn will be warm enough.
