We got our first egg tonight! The poor thing lasted only about 10 minutes in our house due to a very nosey cat pushing it off the drying rack, but never the less--we FINALLY got one. I did notice though that the shell was pretty weak. I know oyster shells are supposed to make them stronger but I don't know where to get any. Anyone want to fill me in on stronger shells if oysters aren't an option? or maybe where to get the shell from?
