Pretty good rule of thumb, watch the expiration date, & you want to use them up in a few days from purchase. Read lots of so-called rules re freshness - i.e. put them in a bowl of water & if it floats it's gone bad. Use em up when they're fresh.
I rarely eat eggs unless it's a great recipe or an ingredient in a recipe I'd like to make. On occasion, I'll prepare an egg dish. A while back I posted a querry about egg substitutes. I saved the info if anyone is interested.
A thought I had at one time, was scrambling them, pouring into an ice cube tray, freezing, then popping them out as needed. Haven't tried that yet & don't know how long they'd last.
P.S. Also read some people wash them first, as they come from a chicken's whatever (city girl here).
