Would if you know for a fact they are not fertile because you have no roosters? Are you suppose to Let them keep some of their eggs anyway and let them pretend or should you keep taking them? Also how long are eggs good for out in the coop if they are not collected right away? I mean the kinds you plan to collect and eat.
If a Silkie is broody she will not be laying eggs. At least mine don't.
Silkie broodies try to go sit on newly layed eggs by other hens so we collect them asap before the broody heats up the egg. Sometimes a Silkie goes broody just at the sight of a couple freshly layed eggs in another nest! We collect eggs as soon as we hear the egg songs because the LF Ameraucana is a klutzy girl and doesn't mean to but she steps on and can break the eggs. I understand Jersey Giants often break eggs because they are so big and heavy.
No rooster - no fertile eggs.
We keep our collected eggs 2 or 3 days on the kitchen counter and then fill up the egg carton all at once. I heard up to 2 weeks eggs can be kept out as long as there are no temperature extremes like very hot or very cold in the room. My uncle ran a chicken ranch and kept eggs up to 3 months in his large refrigerator cooler before going to market. Eggs in supermarkets are probably older than that - at least they taste old!
