I dont know which hen it is, but I know it's one of 2 for sure. A couple of times now over recent days I've gone out in the morning and collected 3 lovely plump brown eggs from my lovely plump chickies, but then at about 5pm-ish one of them has come in the porch and laid a completely shell-less egg on the floor. I didnt think it was possible for a hen to have 2 eggs on the same day, and they are getting a good mix of layers mash/pellets with some green treats (cabbbage etc) and chicken tonic and calcium supplement given throughout the day. The following day there will be only 2 eggs in the coop, then back to the 3 again for a few days before the soft egg thing repeats itself. None of the chickens are showing signs of illness apart from one girl with possible gleet, though I dont think it's her that's having the egg problem as her eggs are quite distinctive. What is going on?
