I am envious of your Bresse! I’ve been looking into them a lot lately- not sure I’d have the balls (

) to caponize, but I am so intrigued by them as a meat bird.
I’m still waiting on 6 eggs- some of which have pipped - but the rest have all hatched! My divider between the two breeds was useless, they’ve basically trampled it- thankfully the Wheaten Ameraucanas and BCM’s look different enough that I can tell who is who.
How long do you leave everything in the incubator before opening? The chicks are running madly over the remaining few eggs, but I don’t want to open it too soon.
