This is going to sound hugely insensitive and I apologize for that. If you aren't prepared to incubate eggs and you aren't prepared to feed an entire clutch until you can sell the babies, don't incubate the eggs. Nothing says you HAVE to hatch the babies. If you don't want to just freeze and toss the eggs, but still don't want to incubate and feed a new clutch, see if you can find a breeder who has incubator space and let them have the eggs.
