Hi Im pretty new to raising chickens. I have a trio of Seramas. A Buff Rooster, a white with chocolate spotting hen and a black partridge hen. The Partridge laid 8 eggs and two were infertile. And she is now sitting on 6 of them. Its October and we have temps from 40s- 60s here at night. What linings or materials could i put in the nest to keep them warmer. "m afraid the two eggs didn't develop cuz it was too cold. My father told me to use carpet as the base, of the nest. Should I? Im new to raising chickens, and I really want the eggs to hatch? What materials should i use? and what are some stuff i shouldnt use. Thanks
