Definitely candle to make sure.My Golden Laced Wyandotte went broody last year in May and hatched 3 chicks. This year, I was disappointed when May came and went with no broody hen. However, she DID go broody in August!! I just happened to have a carton of fertile eggs from the local farm that I put under her. She started with 12 eggs, but 4 ended up breaking. Two have hatched (day 21 was Thursday) and I'm about to lose hope that the others will hatch. I don't know if I should wait till she stops sitting on them or if I should candle them to see if they are duds. Is there any hope at day 25?
