Indeed, a multiple gene male can be a good plan especially if you have females with only one or two genes because you can breed the male to several females in the same season and can still have different looking babies with different combo’s. With keeping babies you can mix them again for new combo’s. Beside that a multiple gene male can keep you going or several years and still give you different offspring. Didn’t breed myself yet but am already for more than a year gathering all the information I can get. I heard that not every female and male are a match. Sometimes they simply “don’t like” each other enough to breed and it is good to have a back up male, so before you sell your ghi male… On the other side you still have the scales head male but do you want to use that as a back up?
It is also good to check on the type of Bel you want. Do you want super mojave with purple head, or a really white one like mojave lesser/butter? Also in the dark morphs it is good to think long run. Now mayby your happy with every healty baby you get and are going for Bel’s and super Ghi’s, but if you had them for like two years, are you then still so happy to see these comming out of the egg’s or do you like to evolve. And do you really want the only dark ones or do you want to also throw some contrasting colors inside? Then maybe enhancers like yellow belly, pastel, enchi , fire, OD can also be a good plan even through they are not dark but make the patern pop up on the dark basic colour. Try to figure out what makes you happy today, but also keep you busy longer. If you have a group of healthy breeders, it is a pity to sell them because you can not evolve anymore. You never know how good the new one is going to be and every new animal you bring to your house also creates a small…but still new health risk. Besides that, if you had an animal for many years, is it really so easy to sell it? I can only talk for myself but I hope I can keep my startergroup till I’m old and grey, because i am too attached to them, and because I get attached I disided to take two to three years to get a breeding group but with genes that can be mixed in so many beautifull combos that it will still take me at least ten years or even more before I hit every one of them.
I will not tell you what to do because I don’t know your budget or space and we are all different people, but am just trying to make you consider some different sides so can be happy with your snakes today but also in the years to come. Check morph market for possible combo’s and check what you need to get them, and if you got that one, what is the next one and can you also get that one. There is also a topic on this forum with all kind of dark morphs and there are really a lott of breathtaking ones there.
Good luck to you!!!
