I have a broody hen that wants to start her own family. I am will to give her some eggs to hatch but am just concerned on weather or not she can keep them warm enough. Temps average it the low 70s this time of year but with the cold fronts passing through it can get down to the low 40s and up as high as the low 80s. Can she keep them at the right temp for them to develop or should I wait until it warms up a bit?
