Yes that's what I suspected, here in Oz, we have limited blood, and I have 2 splits, so that should help alot..... heaps of white chicks die before 4 months of age here.... Apparently. I just wanted to ask, have you ever heard of shadowing in whites? As the Peacocks Australia or Australian Poultry Forum (run by the same guy)
have this article about it, I just wanted to see your view on this, because I don't know if it reads right.

Never heard of shadowing or noticed anything like that. I've personally raised whites from couple generations of no white breeder birds(example: split bred to non-splits, splits to splits but whites were sold & kept the splits and so on) and can say the whites from these are 'as pure as the driven snow'.
Reading his post, I could not help but wonder how did he get his splits? All I saw was whites to splits, white to white then back to white to splits. Nothing on
out crossing whites to IB "without a drop of white blood". If they're not doing out crosses, then it seems like a bunch of inbreeding. (it's not an outcross if a split from a white program like that are being used..)
If the whites in Australia is the same mutation in USA, health really should not be a problem at all... they are raised exactly the same way as any other color. Growth and survival rates no difference at all from IB.
Well i'm thinking the only shadowing is either the birds shadow itself or dirty birds
