Hi all. I'm new to the BYC world, and just started my first flock this past spring. My ladies are finally laying but there seems to be a problem with cracking. Many of the eggs are turning out to have a small somewhat circular crack at one end. I've been mixing oyster shell into their feed since I started them on a layer feed mix (half layer feed, half grower until they started laying last week, now all layer) so they are getting calcium. Maybe it's not enough? Or is their not enough padding in their nest boxes? I try to put a nice cushion of pine shavings in, but they scratch it all out, even though there's a lip. I don't want my eggies being cracked anymore! Can somebody tell me what the best fix is? I have no idea what to do. Also, how long will these cracked eggs keep? Should I try to store them at all or eat them same day? Thanks in advance!
