My chicken Esmarelda laid her first egg on friday, and another on saturday. On sunday while checking the nest box, I found an egg with a very soft shell, in fact it had split and the yolk had come out of it. I have cleaned out the coop, but main concern is, has poor Esmarelda laid too many eggs for a newbie? Is this why the shell was so soft? There were no eggs today at all. So I suppose what I am asking is does my chook have a deficiancy of some kind, or has she just overdone the egglaying?
