Candled to check for fertility today.
My Bielefelder rooster is molting so no fertile eggs from him.
My young Buckeye rooster is doing great 17 fertile out of 20.
The shipped Brown Leghorn eggs are 12 fertile out of 13.
Since you started to help some blood may have glued it to the shell.
After 24 hours from the last time you were "helping" it I'd see if you need to help pull back the top part of the shell and let it push out on its own.
If you wouldn't have intervened this wouldn't have been a problem, sorry. 🤐
How many hens does your rooster have? Sometimes they have favorite hens they like, sometimes when they're nice they aren't aggressive breeders. I'd take my friendly roosters any day.
Also in the extreme heat they might back off breeding. I hope you'll try again.
People buy straight run chicks all the time. You can sell them as straight run and then they can decide what to do with the cockerels.
I know you may not like to think of it when they are cute little babies, but people need home raised meat too.
I just wanted you show you all my thread on candling dark eggs and what to look for. 😊
