Mother Hens do not sit on their eggs; they squat over them. Their legs bear most of their weight, and the nest provides enough support and insulation. This coupled with the chicken mom’s underside ensures that the eggs are safe, warm, and secure.

Another thing is the hen’s body structure. A chicken isn’t as round as one might think. Looking at its profile, one will observe that the underside is more V-shape than its round, like a boat with a rather pointy center. This pointy center is the breastbone, and the area around it is quite featherless. This allow for more heat to pass from the Mother’s body to her babies. Also, each side of this V-shape; for the reason that they are throughout like somewhat than produce, permit a chicken to sit on her eggs with out them end up omelets.
