Hi , i have had several broody hens sat on eggs of which 13 have hatched but i know find the hens getting restless and not sitting n remaining eggs, today on going out i find the eggs have started to chill off, I've set the incubator going but recomended 24 hrs on in advance, Asking as hens not sitting on eggs would i be best sticking straight in incubator , walking round with them in my bra for heat or what for the next few hrs ?
