Hello everyone I have four Rhode Island red hens and a domineqer rooster I have been gathering my eggs for a few years everyday but have decided to try and hatch some since I have a hen that is wanting to set on them. My question is this she sets on them for quite some time several weeks and then I go to check on her and some of the eggs have been broken and are rotten. How do I keep the eggs from rotting before they hatch is there something I am doing wrong or what plZ help thanks
