eggs cold

Hi all, At the moment I have 2 fertile frizzle eggs under one of my broody Silkie hens... today is day 19 and one of the eggs has started chirping. I know that at this stage I probably shouldn’t be candling the eggs, but this afternoon as I let the broody hen off of her nest to go to the toilet...

So, we are new this whole thing, but I had a australorp go broody on me so we decided to give her a couple fertile bantom eggs to hatch. All has gone very well to this point. We have her separated and she is a devoted mom. She only leaves the nest once a day to peck around the yard, get a drink...
