I have 14 CX chicks in my basement brooder. They are almost 3 wks old and growing quickly and really feathering in. Our days are in 60s-70s but our nights are chilly in the 30s. I would like to get them out into their chicken tractor ASAP but am worried the nights are too cold! Please reassure me they will be ok with a heat lamp at night.
) Otherwise, they start out in the uninsulated coop right away. I have heat lamps on them and plenty of room for them to either be under the lamps, or away from them if needed. I don't use a thermometer to know whether or not they need more or less heat. I watch them. Yep, I will even check on them at night. If they are huddled under the light, they are too cold - lower the lamp. If they are trying to get away from the lamp, they are too hot - raise it. If they are dozing, peeping contentedly, eating and drinking, they are comfortable. I believe it would be perfectly fine to put them out now and have the heat lamp on them at night. Just be sure to check on them the first couple of nights to see how they're doing. I would like to add, that I'm from MN, so I do know that it works to keep them out in a coop at night in chilly weather.
