I had written a post about some chicks I have coming next week. It is a bit late in the year to be starting a flock of chickens in Maine, but I couldn't resist. I will be brooding them in the heated basement for 5-6 weeks, then they are heading to the coop, which will put us around the middle of October. Temps for Maine at that time are generally around 40-50 daytime, 30-40 lows at night. In the brooder, I will be using the Ecoglow, and I have read they generally stop using it around 3-4 weeks of age. So they will be used to not having heat/light directly on them for several weeks before they move to the coop, but there is a good temp. difference between the basement and outdoors of course! So I had asked on here if they should be ok in my unheated/uninsulated coop around 6 weeks of age, and everyone thought they should be fine as long as there are no drafts. But I have several friends who own chickens (one is a neighbor down the road, and one is my pastor's wife who will be getting a batch of chicks the same week I am who lives about 20 minutes from me) who swear my chickens won't make it if I don't have a heater in the coop, especially until they are 8-10 weeks old. So now I am worrying!!! I hate the idea of a heater in the coop, as I will have shavings and straw in there for insulation during the winter (plan on using sand during summer months) and I worry about a fire. How many of you use heat lamps in cold temps? Is it really necessary? My coop is about 3.5 feet by 6 feet, and 5 feet high. There will be 6-7 cold hardy breed chickens in there (7 if all the chicks survive shipping next week), so I was hoping they could all just pile together for warmth, but my neighbors have me worrying now. I found a ceramic reptile heater online that is 100watts that doesn't create light, would this work alright? I will plan on having it in a ceramic socket clamp lamp as well. I don't have electricity in the coop, so I will have to run an extension cord. Do I just bite the bullet and order the heat lamp or am I worrying needlessly?? Thanks for helping out this chicken newbie!
