I purchased chicks from Cackle hatchery and had planned on having them be raised by my broody hen. Unfortunately, she violently rejected them and I am left to raise the babies now. I have always had broodies raise chicks for me so this is new territory. The instructions from Cackle said not to use a heat plate for the first week. Is this necessary? I am nervous about using a heat lamp (though that is what I have on them now and it is secured well), and I am having trouble regulating the temperature because it is summer and they are in a small room - the whole room is getting quite warm. I have had them for 3 days now, can I move them to the heat plate a little early? Thanks for your input!
