I have a couple of charcoal hens. If they laid eggs, and if those eggs were fertile, it's not something I would hide. Many breeders could use that information to know that it CAN happen. I'm not a breeder (my birds are pets) and I don't have the resources or knowledge or desire to spend 9 years working with genetics. While I admire the people who do have the time and patience, it's not on my radar. Many of us probably fall into this category as hobbyists. I support the breeders and their work, I just don't do it myself. Thank you, AquaEyes and the other genetics experts, for sharing your knowledge.
