I have a gold laced bantam wyandotte sitting on 7 eggs. I have also collected 10 more of my own and put in my incubator. Curious to see if the cockerel has been doing his job!
Good luck! Be sure to mark the eggs under her if she isn't separated. Hens are sneaky and will continue to lay eggs under your broody or your broody may steal eggs from other nest boxes. lol

The other eggs it's way too early to make the call. They have a different amount of cuticle with makes them slightly more difficult to candle.

the eggs are all cold. She has been sitting on them last night and then part of today. I've put them into my incubator but I guess the chance of them developing is pretty much close to 0?
