Hi everyone…I have a broody hen who has been sitting on two fertilized eggs for 27 days today. She started out with 4 eggs, got rid of two within the first week and has been sitting on the other two. I candled these eggs after about 11 days and could clearly see blood vessels in the eggs. How much longer should I let her sit on them? Does it normally take this long? Everything I have read says 21 days give or take….Any advice would be greatly appreciated.
