I seem to be getting a lot of eggs from my quail, both coturnix and bobwhite, that have double yolks. Is it ok to incubate these eggs? Will it cause problems? If it is not ok is there some way to cull these eggs reliably? I get a lot of large eggs that don't have double yolks so just going by size isn't reliable. Thanks in advance you guys always have the answer I am looking for.
