I bought some BCM hatching eggs a few months ago. I had a ridiculously low hatch rate on them. I ended up with just one. Are they just harder to hatch then other breeds? I had much more luck with the other breeds that were in the incubator at the same time. The one I do have started out with light leg feathering but it has almost entirely disappeared now. I don't know whether they'll feather out more or not. If anyone finds a good source for BCM eggs (or better yet, blue copper!) let me know. I'm ready to try hatching some more of them. Heck, I'd be pretty happy if I could find a nice cockerel even.
I have heard (and from my experience) that BCM eggs do not handle shipping well. I think swedish flower hens and some other breeds are like this. I have incubated shipped BCM eggs and gotten 0-4 to hatch yet I can get 100% on my own BCM eggs from my flock.
