I have 2 female pheasants and one male. One of the females just hatched 6 chicks. I went to TSC and a worker there told me I should bring them in and put them under a heat lamp. I also read online that if the mama is laying on them to keep them warm then they should be fine. It will be in the 30s overnight and I want to make the right decision. I have a heat lamp in the pen but I'm very worried.
