Wait, were we not both talking about using a het pied animal? Would not the chance of producing a het pied animals be the same regardless of sex gene distribution? I totally agree visual pied animals would be ideal for gene production but also the most costly. Lets talk about prices. You can get a yb pied male for around 600 and I am guessing a od het pied would be around 300-400, for a total of around $1000. The only yb od het pied male I could find was listed for 1500 and a deal on a female pied would be 300, so about $1800. I am really having trouble seeing where that is a better value since you get the same offspring percentage. Not to mention you could pick up a pastel het pied female and produce some beautiful pastel yb pieds for another $60. Help me out here to understand where you are coming from, I am honestly curious.
