My pullets are 20 weeks and have been wormed and treated with amproline. So i am pretty confident that there is no internal parasite problem also have checked for external - none. The problem I'm having is they are laying eggs in the nite off of their roost and the egg shells are soft but then during the day are a few normal eggs. Any suggestion out there?? They are on layena and have free choice to oyster shell also giving them yogurt twice a week..
