If I were still raising buttons, I'd do a series on them. Unfortunately, I didn't bring my buttons with me when I moved. I would rather like to have them again someday, though.Fair enough. We have no idea what we're looking at, so we'll probably leave it a bit longer. We've seen lots of videos of people candling coturnix, but nobody seems to bother with buttons. I'm assuming it's because it's hard to see anything going on in something so dark, and tiny.
