So we are moving our 2 wk and 3 wk chicks outside today. It was 65 today and the low should be about 40 tonight. I have a cardboard suround for them w/several inches of pine shavings and two heat lamps (250 watt ..one red & one regular). The garage they are going into isn't heated and now I'm having second thoughts. It would be so sad to lose any because of the cold. I have a thermometer in there and it's fine now but I'm worried about it dropping in the middle of the night. They need more room than I can provide indoors at this point. So they need to go to the bigger brooder out there. Does anyone else have chicks in an uninsulated area that gets pretty cold at night? If so do you use a space heater or do you feel lamps are enough? Thanks!
