Aussie Finch Forum

I am new to star finches.
started with two pairs of normal stars that have red head.

pair 1 --> gave me two cinnamon hens, so the dad should be split to cinnamon i believe.
pair 2 --> gave regular star finches

now that i got two cinnamon sisters, the bug of yellow bodied star finches bite me and i got two pairs of yellow bodied star finches and a cinnamon male.

Below is what i have right now
1 cinnamon male
2 cinnamon hens (sisters and own bred)
1 pair of red head yellow bodied
1 pair of yellow head yellow bodied


i dont want to pair yellow bodied to yellow bodied bird if they will weaken the stocks

thinking about below combination

1. Red head yellow bodied male X red head cinnamon hen
2. Yellow head yellow bodied male X red head cinnamon hen
3. Red head cinnamon male X yellow head yellow bodied hen
4. red head normal male /cinnamon X red head yellow bodied hen

What could be the potential outcome of these pairings?

To get yellow body the fawn mutation is required as yellow body is two mutations cinnamon and fawn.
Cinnamon is sexlinked recessive mutation and fawn is autosomal recessive. You can't get split cinnamon hens only split fawn hens. If you have cinnamon hens you to put yellow body cocks to them as yellow body carries fawn. It is confusing but you to know the genetics of cinnamon and fawn and how that works.
In cinnamon the rump/tail is pink and fawn pretty stays the same as normal. Hope that helps abit.

what do my pairings produce?

No1 all cinnamon and all split to fawn.
No2 same as no1
No3 same 1 and 2
No 4 same as 1 2 and 3
Taking that none of the other birds that are not yellow body are split to fawn
