A Rattery owner/Friend would like to buy/trade one of my male dumbo polydactyl rats to add to part of her breeding program, she lives in NYC (6 hours frome me) But I'm a little concerned about letting her have one of my guys, because she breeds Manx or Tailless rats.
I don't want to be rude to her, but frankly I think that the overall health of any litters would be severly compromised.
My rats are all Polydactyl, or carriers of this trait, which is for the most part a male dominated trait, breeding polydactyl females with a non-poly male results in no poly babies, and the pup have other health related problems that we don't even want to get into, but she's wanting to start a line of Hairless Dumbo Manx Rats, I've read that you should not breed tailless females, unsure of the why's but my question is..How do I let her know what my concers are without offending her? I really do not want the litter(s) or resulting pups to be of poor quality, and health. I can't (and don't want to) imagine the genetic deformities from so many recessive genes!
In my litters my average is about 15 pups per litter, with a very low female to male pup ratio with my Polydactyl Line, on average I'll have about 3 haired pups per litter, most being female, and either 1 or No female hairless polydactyl.
For instance in my last litter 1 female hairless polydactyl, 2 haired standard foot, 1 haired male 6 male dumbo hairless polydactyl (3 black self, 3 PEW)
