It gets overwhelming very quick and with no help you can easily exhaust yourself. You can be a breeder and maintain good finances, but a commonly used quote is it takes money to make money and this is true in breeding ball pythons. Mouths to feed can add up quickly if you're not selling anything, and some morphs do drop very fast. Yes ball pythons do drop in value fast with morphs, however if you expand what you breed you can change this. For instance GTP's have a steady value, and if you keep the proper documentation you can sell your animals for more. Overall though being a breeder is basically like a production job and it's a hobby, so hard times can easily come. There's so many things to factor in which also suck but I wish you the best.
I don't breed anymore because I was too picky of a seller, I would screen customers to make sure they planned on taking proper care of the animal. But yes, any animal that dies is sad.
