I have 21 RIR hens and 3 roos. A gentleman that has a 250 egg incubater (sp) wants me to save eggs for 4 days till he can pick them up, which is ok. My question is if he doesn't come get the eggs or changes his mind would those eggs be ok to eat or sell. I usually refrigerate them same day collected. These I would not. Thanks in advance for any help.
