seagreen finch

[nicko]

How do you determine the sex of the seagreen finch.

[Tiaris]

Same as normal RFPF. Male is slightly thicker set, more vibrant colour, more extensive head colour with a decent amount of head colour behind the eye, longer more prominent tail "pins", often with a few coloured feathers on the vent (orange in seagreen) when fully coloured & only males trill. If bred from normal phenotype RFPFs, any seagreens are hens (from a split male) as the mutation is sex-linked recessive. Hens are hence more common.

[nicko]

Hmmm, the ones I've got look similar, no colour past the rear of the eyes, both have orange tail feathers but one has more orange (near the vent) & head colour a little different - they're only a couple of months old.
If the buggers sit still for a bit I'll see if I can get a picture

[Tiaris]

Did you breed them?

[nicko]

No I got them as a "pair".
I've not had any seagreens before & I think I may have 2 hens, apparently both parents are RFPF's producing seagreen young

[Stu]

apparently both parents are RFPF's producing seagreen young

Both parents are 'normal green' ?

[nicko]

Yes Stu I believe so

Split Cock (normal in appearance) X Normal Hen

produce

Split Cocks (n.i.a) + Normal Cocks + Mutant Hens + Normal Hens . .
In all sex-linked mutations . .




Not a recommended pairing because, while the hens are 'definites' (hens cannot be split for a sex-linked trait) . . cocks will need to be test mated (over a period . . unless a mutant hen appears in the first clutch) to prove their genetic make-up

[nicko]

Thanks Arthur, visually trying to decide if I have 2 hens (which I think I have) or a pair, I think I'll wait & see if one exhibits a mating ritual

[arthur]

If they've DEFINITELY come from 2 normal looking parents . .

They are DEFINITELY 2 hens . . 100%

Put a cockbird in with them and you'll see a mating ritual
