I am amazed.....as I have read repeatedly that you should not attempt to hatch pullet eggs until they have been laying for at a least month. A friend had a broody hen but no fertile eggs, so I gave her some from my senior flock just before Mr Rooster was rehomed and she really wanted some of the Wellsummer and EE pullet eggs I had. I told her they may not develop, hatch or might be deformed, I was pretty sure they were fertile covered by my new Welsummer cockerel as I had seen him doing his duty well and checked the yolks for fertility out of curiosity. 2 of the EE eggs hatched, she'd been laying about 3 weeks.....and one of the Welsummer eggs hatched, she'd only been laying about 10 days/7 eggs so far. Tiny little thing but appears to be hale and hearty running around with her hatch mates, markings indicate female too so double good news! Wellie chick is the smallest at the bottom of the pic.
