In my opinion, buying a pair of hets is not the best way to go. I think you are better off just getting the male het and breeding him to a few normals. That way you have multiple possible het females instead of putting all of your hopes in just one female het. I have done MUCH better going this way than in projects where I just bought a pair of hets.
An example is my Lavender project. I paid 7k for a pair of hets. I could have got just the male for 2k. I ended up breeding the male to some normals and raisng up the females. The 100% het female ended up being a female that laid either slugs or did not lay at all for her first few breeding seasons. I actually produced quite a few visual lavenders from my poss het girls that I raised up before ever getting one from the 100% het female. Could have saved myself 5k. Going with only getting the male may set you back one season, but then you will have multiple females laying when they get up to size and you don't pin all of your hopes on one female.
I went the het male route on my clowns as well. I bought a het clown male for $400 and bred him to normal females his first season. I got eggs from 3 poss het girls when they were only 2 years old, proved out 2 of them and hatched out 4 visual clowns that year. I did really well on that project. It was less then 3 years from the time that I bought my het male to when I produced visuals.
Especially with stuff that is still high in price het males are the way to go. I think Toffee's are going to be my next Het male project.
I've never even thought about it that way, and it sounds like a good idea.
What if you add another gene into the mix instead of a normal female? Would it effect it at all? Like, het pied to pastel girl, het pied father back to pastel poss het pied female?
