I wasn't meaning to say it wasn't worth it, just at least to some. Just offering my opinion. And just to play a little devil's advocate, there's the responsibility of properly housing them, feeding them, and finding them homes. Finding homes for normal corns is tough - you almost have to give them away; especially with morph prices being so low.
You're absolutely correct that from a purely hobbyist part, breeding normals can be a very worthwhile experience, just so long as the person knows what they're getting into before hand.
To the OP: there's a good chance of them being het for something. Amel, anery, and hypo are all fairly common in the gene pool of corns.
I've had amel, anery A, charcoal, and hypo all pop up in my collection with pairings that had no history of any of those genes in the lines they came from. They were all floating around and sheer luck ended up pairing hets together.
