It may be that something hinky was going on with the availability, but... I own a nail salon, and I've had someone call and want a particular appointment time and I've been full for the entire time frame or particular slot, we book something farther out (or not at all) and then five minutes, (or twenty lol) after we get off the phone I get a call from the client in that exact time slot call and need to switch to a different time! I always feel a little weird calling the first client back, like they will think I am doing something weird, but it's just the way it happens. In my 5 years of owning a salon this has happened MANY times. I do think anytime you are dealing with people and their schedules and what they want, things like this happen. Of course, you do have to follow your own instincts!
As to the pedigrees - I guess I can see why you might want to keep someone from forging a pedigree or somehow using your pedigree info. We run into something similar in the nail industry with posting pictures online - people steal your pictures and post your work as their own. A lot of nail techs make a big deal out of watermarking their work so this can't happen. Personally I think watermarking can take a beautiful picture and make it not so beautiful to look at, and sometimes even hard to see the intricate designs in the nails, so I don't do it. Plus, if someone took a picture of one of my more intricate work, good luck to them when their client asks them to do the same work on them! I never personally feel like I can be harmed in anyway by them being cheaters, and I think they will have their own natural consequences down the road! I guess I can see both sides, but prefer just not owning the stress of worrying about it.
For myself, I bought the pedigree for my rabbits because I was a bit interested in the genotyping and figuring out what color possibilities we have with our rabbits. I didn't ask, but the breeder actually sent me a picture of our does when they were in the nest box with their litter mates, and it helped us (along with the pedigree of course) to backfill their parents genotypes and then fill in theirs. With Shaggy, she sent a picture of him with one of his litter mates - a REW, which allowed us to backfill his sires genotype (a broken Red), so we knew he carried the recessive REW gene. For this reason I don't think I would ever buy another rabbit without asking a lot of questions, because I will likely be looking for something specific.
I think that if I ever sell breeding stock I will include a 6 generation pedigree, and I have added a field in Kintracks so it shows the genotype - or at least how much I have figured out. I think I will also include pictures of litters, along with information about weights, number in litter, mortality rates, etc. Since I am already tracking and compiling all this information it will be very easy to provide it to the purchaser. If someone is buying breeding stock, it would be nice to give them peace of mind - look, this is the average number of kits from his/her Dam, weights, percentage that make it to the freezer (or sales) etc. Transparency is the best way to breed trust in my experience. Plus, who knows, if someone is just interested in breeding for themselves, it might cause them to start exploring all the possibilities and REALLY get hooked on rabbits and doing more with them, which is good for all of us in the rabbit world!
