This is my first time having chickens. Of my 13 ladies 3 have started laying. One of them, an EE, started laying last tues. and gave me 3 green eggs ( she is 20wks old). They were small eggs but otherwise perfect. She then laid 2 eggs that had a white, a yolk, and a membrane but no shell. Today she laid an egg that had a very thin shell, almost non-exsistant but I know it was hers because it was green just like her others. My other concern is that she had been laying in the nest box but the 3 soft eggs she dropped from the roost. I'm hoping this is just caused by her system "figuring things out". BTW the other 2 that are laying ( a rir, and a bpr) are laying an egg a day for the past 6 days which have nice solid shells.
