My silkie is trying her heart out to hatch some eggs under my back deck, it is pretty Inaccessible to me since there is only about a 3-5 inch gap to get under the deck. i'm worried she'll freeze to death trying to hatch them since she doesn't get off the nest but in the early morning to get some grub. if she makes it w/o freezing, is it possible for the chicks to survive naturally w/ their mother? lately the temperature during the day is 40's and at night can get down to 7.
