This evening I went out to collect my eggs and noticed that a hen was sitting in one of the nests and had also been there this morning. She was hunkered down like she had started going broody and had three eggs under her. The eggs were not there this morning so she has probably been sitting on them for about 8 - 9 hours. The eggs were very warm from her body. I collected the eggs but wonder if they are still viable to eat after being under her all day. I assume it takes longer than one day for the eggs to no longer be viable but just want to be sure and find out just when the process does begin for the chicks to start growing. Any suggestions?
