Hello, I've got a hen that lays LOVELY large blue eggs! I do not know what she is, I was told a mixed lavender? Not sure? Anyway I really want to see if I can hatch some chicks and see if they lay blue eggs. I have never hatched eggs before, I've read a little bit about it, but what I want to know is, can I use any cockerel? And what are my chances of getting chicks that lay blue egg?
