I bought six, one year old hens last Friday. Friday..I had 2 eggs after we had been home only two hours. Saturday I got 4 eggs .....Sunday 5 eggs and today....5 eggs. Should I be worried that one of the hens is not laying? Is there a way to tell if she needs to lay? Can she get backed up? I check for eggs as soon as I see one leave the coop so I'm pretty sure the eggs are not being eaten. Is it normal to have 6 chickens but not get 6 eggs in one day?
