My first time broody hen hatched three chicks and left the other eggs... the eggs are chirping at me! This is day 21! (Some eggs were set two days later than the others). I brought the eggs inside and I do not have an incubator. I put them in a pan with heating pad, a wet paper towel, and covered with syran wrap with a inch hole cut in it. I have a Styrofoam cooler but I have no idea if or how I should use it. I'm so frustrated right now. I'm scared about those innocent chicks she left to die. I hear one chirping at me and two have obvious noises or pecking of some sort coming from the egg. Please help...
