I share your love for corn snakes. They’ve been a source of great joy for many years in many ways, and breeding is a big part of that for me. Kudos to you for asking questions and looking towards plans before actually pairing animals. Not everyone does, and the animals can suffer as a result.
Figure out what you’d love to see, and work toward that. Just as importantly, if there’s a look you really don’t want, that’s something to consider too. Check out examples of adults here on MorphMarket by filtering your search for animals with “adult” maturity and availability of “all,” which will also show animals sold in the past. Peruse the Morphpedia. Look at iansvivarium.com and at the Facebook group Cornsnake Morph ID Help, which is solely about morphs and has many example photos.
Get familiar with how genetics work. If you understand recessive, dominant, and incompletely dominant you’ll have a handle on how an animal’s genes will fit into your goals. MorphMarket has a calculator here: Gene Calculator - MorphMarket . Once results appear, you can click on them and see examples if they exist in the system. There’s also a calculator on iansvivarium.com.
I strongly recommend against breeding any animal whose genetics you don’t know. There are many good, serious breeders who give you solid information on an animal’s genetics which you can use to make short and long term plans. Good breeders come in all collection sizes. A person who produces a clutch of two now and then may be much better about record keeping than a person who produces hundreds of animals yearly for mass market. Of course, you can look at visual traits and know some things. Depending upon your goals, that may be enough. If you want to produce Anery Motley beauties, you can look at the animal and know at least if it’s homozygous for Anery Motley.
Once you figure out a breeding goal, start looking for your foundation animals. When you’re considering animals for purchase, it is best to buy those who are closest to your goals. There’s nothing at all wrong with buying animals who have desired hets, and it’s a sensible way - sometimes the only way - to get to your goal. Do consider that it will take years to prove a hatchling’s possible het, during which time you’re feeding and caring for the snake. The difference in cost between a ph and a visual may be less than the cost of those years. I’m not saying not to consider price, of course. Just consider it sensibly for the long term.
If you decide that you love Sunkissed, working towards a long term goal with the male you have can make sense. Since any breeding goals are really a years-long commitment, if Sunkissed doesn’t fire your passion, it’s okay to consider another male. I would not consider breeding the classic/normal females with unknown hets. The only exception is, unless by classic you mean actual high expression Oketees. (I don’t mean typical classics labeled as Oketees, nor typical Amels called Reverse Oketees.) There is a market for high quality Oketees. If that’s the look you love, it’s also a project which can make sense.
Do plan to keep all your hatchlings for months, possibly years. Maybe you’ll sell the ones you choose to sell immediately, but if you’ve planned on them not selling, you’ll be prepared to feed and house them. It can happen.
Breeding corns is fascinating thing. Their genetics provide vast scope for beauty, and their personalities are intriguing. I love watching and handling mine. I love pondering possibilities. Hatching season is wonderful, though sometimes heartbreaking as well. It is lot of work to do this with thought and care. It’s also just a lot of work, lol. I truly wish you joy in the journey.
