The problem....as I understand it....is that those 6 youngsters that did not have a visual tick, may well in one or two generations down the line, start to throw ticks in most or all of their young. It is in their genes. If the 'good' un-ticked birds are cocks, & you use them liberally, by the time the "ticks" appear, it could be all through your stud ?
I have just bought some clear Lipos from the Continent & I am told that if a 'tick' appears in a nest of young, they all "go", as the top men over there do not want to run the risk of 'contaminating' their stock. It is different in the Uk ( & Australia obviously) where classes are laid on.
The opposite argument is at the root of the problem in birds like the Lizard where light marks are not identified in what are otherwise 'self' birds, & the birds are used for breeding, proliferating foul feather.
At least with a 'tick', in many cases it can be seen .........although I fear at least one ticked bird at the ACS today will be 'wrong-classed'
