Aussie Finch Forum

hi, just wondering if anyone can tell me what colour offspring could i expect from pairing a normal hen to a visual fawn cock ? the hen is not split to fawn as far as i know so would i still get both colours in the nest ?
thanks

Try this . .

There are many others available free on the net . .

The problem with genetic predictions and Zebs, is that there are so many unseen 'splits' and multiple 'splits' that come into play

This may be of use in figuring out what to expect from your stars.

The mutation is autosomal recessive, meaning that mating a colour to a normal will only produce all splits in both male and female young produced. If the hen is split for fawn you will get 50% colour and 50% splits, sometimes more or less of each.

Sorry I’m talking about painteds not Zebs or stars

The comments about what mutations have turned up in Painteds on these 2 sites is interesting. Sorry about getting the wrong birds.

Yes i thought the other members were getting off track with the species. I was the first to breed fawn painteds and specialized in them for many years before they become available so i know what i an talking about in my previous post although i did know what species you were asking about as i looked at the forum species forum for painteds you posted in.
Zeb mutations are a lot different to this painted mutation so don't compare them to fawn painteds. Just a bit of trivia, the fawn painted mutation is not really a mutation for the word fawn as fawn cannot produce black but the so called fawn painted retains its black breast. It's only the back,tail and flight feathers that are affected so the mutation should be called dilute backed but fawn is easier to say i suppose.

they are such an attractive bird i love them !! glad you bred this colour craig, it makes for great variety in the aviary.i have a cockbird that i need a split hen for,probably gonna be hard to find

what is the reason again that we shouldnt pair 2 fawns ? i cant remember

Probably purely for hybrid vigour. As mutations are not always as strong as normals. So my guess is Fawn to split would produce stronger chicks. With some fawn to normal breeding to produce the splits. Don't forget to ring your splits, so they are easy to locate.
