This is a pic of an egg one of my pullets gave us today. You can practically see through it,and the shell is super soft. You might be able to see the indentation in it & I made more with a very light pressure of my thumb. We have 7 hens & a rooster who all get along great. We normally get 6 eggs a day, but our weather cooled down here and production slowed for 2 days to just 2 eggs. Today this was among 6 eggs again. I'm sure it's inedible and will go in compost bin, but what caused this? We obviously think we have a hen who isn't laying since 6 of 7 is our daily count. Now I wonder if this is from the 7th hen just starting to lay.I suppose if I get 1 more egg before day's end, that will answer it. Otherwise, I don't get it. Any advice is welcome. Thank you.
