Yes, but I get the opposite. I seem to get pullet heavy hatches. I don't have fantastic hatch rates yet, what with using still air Hovabators and not paying really good attention to them, but maybe the boys are less able to handle my lousy incubation techniques... who knows? I am always happy to hatch more pullets. I have a couple of quick easy outlets for roos of any age so to me it is all good, but nonetheless I seem to hatch more pullets from all varieties, BBS marans, CBM marans, and bantam cochins... Not a wide skew, but definitely noticeable every time.
PS my temps seem to run just a hair low because I have cooked a few batches by accident before.
