Have a Pair of fawn stars not coloured as yet bred from red male and yellow hen . If i bred these back to red what would be the likely colouring of the offspring ? cheers

Unless your cock is split yellow all young will be red split yellow, same goes for next generation if bred back through red.

Why are you mixing head colours? If you want yellow then breed back through yellow. Better to not mix the mutations.

Its my choice how i breed my birds . How are any mutations established . Anyway a lot of breeders suggest crossing back to reds to maintain resiliance .

No offence intended. I have no problem with deliberate breeding programs, as long as you can keep track of the splits. My concern is more the "surprise" for breeders who have obtained subsequent generations of your birds, perhaps even from other breeders. If you breed back with reds all your next generation birds instantly become "possible splits" and must be sold as such but in time that message won't get through somewhere along the line.

I know the "breed it back" theories well, but with yellow stars I wouldn't have thought it that necessary any more - it's 30 years almost since I had very healthy yellow stars breeding. I doubt the gene pool is that small these days. Perhaps the fawn adds a new dimension though. Still better to breed your new splits back through yellow to establish the new mutation in your case though I reckon, at least until you can create separate red and yellow fawn bloodlines.

I have a similar dilemma, in order to get 3 pairs of unrelated pearl longtails one cock is also fawn so (unexpectedly) I now have two new mutations to develop not one. At least the fawn is sex linked and so easier to track the genetics.

I am not convinced in the theory that you put a yellow bird to a red bird and get better colour.
It is debatable even though some of my mates do it but thats their theory.I am referring to both Stars and Painteds.
As for Yellow Headed Stars,I have had the same blood line of Yellow Headed (normal body colour) Stars in my collection
since 1968 some 42 years.I would put them up against others without a problem. Every 3 years or so I throw a couple of cockbirds in
to add a change of blood(possibly related some where down the track)
The problem now is you can fledge a good nest of Red fronted painteds and one or 2 are actually yellow fronted. :evil: :evil:
