Hey all, been lurking here for a little while learning 'bout these little critters. We got involed with chickens when my neighbor was deployed to Iraq, and he gave the kids a couple of bantoms. Then the wife bought some chicks at the feed store this spring. Well they started laying the first of the month, and the first egg had a real soft rubbery shell. I don't know whether the inside was normal or not, as the wife took it to school to show her kids. From then on everything was pretty much normal eggs except one of the girls was laying an extra, extra large egg that the egg carton wouldn't close with them inside. It turned out that every one of those were double yolks. Well today we got another rubbery egg. It could be the first egg for one of the girls. So I guess my question is why do they do this? Is it a lack of something in their diet? or just one of those thing tha happen. I'll try to put up a picture if'n i can figure out how.
