You could try, if you think they are a bit bored, putting a bit of grain in small plastic bottles (minus lids and labels) and putting them in the run. Hopefully they will be too busy to think about eggs

After 2 days separation, things seem much calmer! One of the three isolated girls is leaving a broken egg, one is okay but the other girl hasn't laid for 2 days.  They seem fairly happy.  There seems to be less aggression and argy bargy so fingers crossed!

I've just found a smashed egg in the nesting box with four others round it, all sticky.  I've had a couple before, but softer shells, so discounted it.

With 9 hens I have absolutely no idea how to find out which one is doing it and how to stop it.  Think I'll just have to put up with wasting an egg a day and cleaning the nest box every day.

Thin shelled eggs may be down to the hens getting older and the same amount of eggshell being distributed over larger eggs, rather than idetary insufficinecy.
