I am just now making friends as an adult, most are not letting me seclude myself from them, or withdraw. And they are all significantly older than I am. Then my barn family is just amazing.
Alright back. I bred ball pythons. Had many many snakes go in and out, raised many, etc. I had a few who were massive escape artists, but I almost always found them, and then I just made sure their tubs were not able to be opened anymore. My corn snake babies? Escaped. All of them. Every time. And I never found them. They are tiny, so I gave up on them haha. Was going to breed them at one point but decided not too.
Whispy just depends on if you want to take that gamble, but I personally wouldn't. Also if the foal ends up not good, it will be harder to tell which parent is bad
Personally, I would wait until RO and then search for what price other WWW and WWE combo WBs are up for brood at. Then you can compare your mares to them and figure out pricing that way. I don't know the WB market so I don't have any other advice than that unfortunately.
I can't sell a WWWs brood who's had WWE foals for even 80k, so it's tough. I find that if you sell premade embryos, they go for way more. I matched mares with top studs (200k fees) and charged 500k (embryo/brood sale for the same mare was never even bought for 150k). Managed to make 300k off my mare (or more!) even tho her brood/unmade embryo wouldn't have sold for half of that.
