Ok so I have 23 assorted full size/ bantam babies who are 5 weeks old today. I will have had them 5 weeks tomorrow. In my basement room the temp is anywhere from 60-75 degrees depending on if we have the wood stove going. When can I cut out the 250 watt red bulb? I have been doing the 5 degrees less every week. I have heard so many different theories lol. Oh and we just had another snow storm so they can't go out for a couple more weeks. We can't get out tractor coop up the hill to our yard until snow melts...
