All my other little hens are laying except the MGB's. I have 4 of them and I have only gotten an egg or two every blue moon since I got them. Is this just how they lay? Also, the shells are very thin, despite the oyster shell that I have out for them. I guess they just don't eat it. Anybody have any comments/suggestions? I want to hatch some of their eggs once I get them a rooster, but I'm not sure how it will work with these thin shells.
