We went away for the weekend and when we came back there were 22 eggs from my eight laying hens. Well that was on Monday that we came back and today is Friday and there has not been a single egg from anybody that we can find. They are not moulting, have not laid anywhere else because I have searched and if there is an animal than it is too tiny to run with the eggs because we have an electric fence and it would have to go through the fence holes, also there are not broken shells anywhere that would indicate egg eating. I usually get at least 6-7 eggs a day so it is strange that absolutely noone is laying. Any suggestions as to what is going on here?
