I tried to refrain from imposing my opinion of inexperienced breeders in my previous post because it's just that, my opinion.
Whether I think your friend (or anyone else for that matter ) should or shouldn't breed is irrelevant because I can't make that decision for someone else's gliders.
IF he's serious about breeding the "right way" have him join the breeding 101 group and learn how to understand lineage, kinship, hets etc and even ask for a breeding mentor that will work with him one on one. They will explain all that and then some and teach him how to safely pair a breeding pair.
I get it to a point but I get lost in the dominant, recessive gene stuff lol my eyes glaze over when I try to understand it all
so while it kind of makes sense in my head it never comes out right when I try to explain it to someone else.
Even if his eyes glaze over at that stuff too there are very experienced well known ethical breeders in that group that will help him pair gliders up safely if he can't do it himself.
"It's really upsetting me bc I introduced him to gliders, basically, but not for this reason. I've seriously been considering "taking" his gliders (bc I know he wouldn't press charges) but I hate to go through all this bc he's just being ignorant."
I get it, but Please don't be that upset. It's a very common thing for new glider owners to want to dive into breeding it's not your fault.
Some will quickly change their minds when they find out it's not a get rich quick thing, or when they find out what all is involved. But others still dive in head first regardless.
If he's acting like he wants to go about it the right way all you really can do is encourage THAT and point him in a good direction to breed safely and ethically. But there are some things he should know before he makes that decision.
As his friend encourage him to educate himself and look past the first impulse to be a breeder because sometimes thats all it is is an impulse.
Besides the lineage, kinship, hets etc... he also needs to look at his location and how many other breeders are near him.
For instance, I live in south west fla. I can't spit out my door without hitting a breeder, n I can't spit far
. The market here is veryyyyyyy saturated with breeders, both reputable/well known and back yard, so selling them isn't easy in fla unless you ship. I live in a 5th wheel and can only manage 3 cages in my living space. Knowing the market in my area/state, and my space limitations makes it very clear I shouldn't breed with intentions of selling. I would be over run with gliders in no time even with just one breeding pair.
Your not only competing with the breeders your also competing with all the gliders up for rehoming. More local breeders will also affect your prices, to compete your prices may need to be lower regardless of color.
Shipping gliders isn't as easy or cheap as it used to be so many breeders are only selling locally.
Depending on difficulty of selling... you may end up with gliders/joeys not finding a home right away. In that case you need space to provide cages for offspring that don't sell. And you need to be prepared to keep them indefinitely. Which can mean money out of pocket for neutering males that aren't sold because at that point increasing your breeding program is only going to compound the problem and you'll end up with more you can't sell.
I could go on, but those few things alone he really needs to think about before deciding on becoming a breeder.
Hope this helps some
