5/6 today but I have a question, one of the 5 was so paper thin it was busted before it hit the nest. all the hens are offered oyster shells and their own shells daily and eat real good. what would have caused it to be so terrible?? is she just not eating the shell hardeners or could she have a problem I didn't know was there. I'll also say I have one that hasn't layed an egg in a month! but not sure which hen it is.... they all lay brown eggs so it isn't easy to tell.
