I have a Serama hen who is sitting on 4 of hatch- to-be eggs. Today is day 21 or 22. It her first time and my first time too. She has been quite dedicated to her duty and rarely leaves her eggs. Her sweetheart rooster has been very patience, and started sitting next to her since last Thursday. I am 99% positive the eggs are fertile. It was my understanding that the chicks should have hatched by now. Any feedback or suggestions would be appreciated. Thanks!
