We have chickens hatched thru out April. We started to get some eggs for about 2 weeks different siZes and then all of the sudden they stopped. We are in northern central MD and the temps have began to drop. Should I be worried that the egg laying stopped suddenly? We have white rock, golden laced Wynedotte, buff Orpington, Cooper Marin, salmon Faverolle... and 2 ducks. All from early to late April. Not sure if something is wrong or if I should be looking or doing something. Thanks for any help.
