you would get 25% pied offspring, not sure how many eggs royals lay in a clutch though

Problem is, you're not guaranteed 25% pied in every clutch... to test this, flip two coins ten times.

Each flip of two coins represents one offspring.

Double heads = pied hatchling.
Anything containing at least one Tails = Possible Het Pied.

How many double heads do you get in your series of ten throws?

Ok, now try it again. Throw your two coins ten times again.

Did you get the same results?

It's a 25% chance that EACH egg will be a pied... which, over thousands of trials, will eventually work out to be around 25% pied offspring. However, one clutch isn't a big enough sample size!

The problem is that Bob doesn't talk to Norma and Billy and Joleen to find out if one of THEM is pied before coming out as a normal.

Thing is, we tried it, with two sets of six throws.

First set of throws, we got:
Four Tails/Tails (not het at all).
Two Heads/Heads (visual pied).

Second set of throws we got:
Two Tails/Tails (not het at all)
Three Heads/Tails (het pied)
One Heads/Heads (visual pied).

The first set of throws is uncharacteristic - we got four results that you only have a 25% chance of getting in any one throw, plus two other results you only have a 25% chance of getting in any one throw.

The second is a more normal distribution.

It's completely chance

Same goes with the fifteen eggs I've got from a corn; this pairing has a 1 in 16 chance of producing Lavender/Anery Stripes. Am I "supposed" to get one if I've only got fifteen eggs? And the answer is: It doesn't work like that - the chance is per egg, not per clutch.

Problem is that you will have to wait 2 -3 years before you get any offspring. Likelyhood is that the first cluth will be more like 4 eggs. You will probably get 1 pied which i assume you will want to keep. The other 3 will only be 66% hets will be worth about the same as a normal royal so its going to be more like 4 years before you sell a pied and make any money back. And in 4 years time a pied will probably sell for about £500 - £1000 depending on how many are produced over the next few years.

So dont buy them on the idea that you will make money on them because when you take into account housing, feeding and heating costs you probably wont make anything at all. Youll probably just make your money back over the next 6 - 8 years
