I don’t have chickens I buy them unwashed at the store, use a certain amount of them in the next two or three days because I planned for them, and then all bets are off for the left-over eggs.
I’ll get around to them eventually, never yet had to throw one away, but they keep longer in the fridge and they need a place to stay anyway so why not there.
Oh and once they near their expiry date hard-boil them, that easily adds another month.
