Many people won't incubate eggs past a week. The recommendation is 10 days or less and most agree that by 2 weeks you see significant drop of hatch rates.
Should be good to go. Thinking about my last statement which I have heard from others I guess its sorta up in the air cause if you think about it if you let the chicken do it she waits until she has a clutch so I'm thinking wait it out till you get the number you want and see what happens.
So silly question. I have 6 hens, well, at least I think I have 6 hens......My girls started laying 5 days ago and my Delaware, Bernadette, was the first to lay, followed by my Blue Andalusian, Eleanor. Yesterday, Eleanor laid her first egg. After I collected eggs, I put them in the fridge and when I cracked Eleanor's egg open this evening, I saw a "bull's eye" and a blood spot on it. Normally I won't worry but I don't have a Roo.....so, is one of my girls just in disguise? LOL
