Who is the sire?

[Guest IB]

I've discovered a pair raising their second round of youngsters have a grizzle in the nest, but neither parent is a grizzle (blue white flight cock paired to a blue chequer hen) so the sire must be one of two grizzle cocks in the loft.

 

But what about the nest mate, a blue bar? Does anyone know how fertilisation works in a pigeon? When the cock treads the hen, does the same batch of sperm fertilise both eggs, or is the second egg fertilised by a second treading?

 

I know the hen has a facility to store sperm for up to (a week?)  anyone know how that works?

 

I know my birds tread between first and second eggs laid.  But I don't know if it is really necessary.

somewhere in the backround there might be a grizzle,

l have 2 blue bars that layed 2 eggs and one chick is grizzle, but i know the cocks grandfather is a grizzle

My understanding of grizzle inheritance is that it does not miss generations. A cock and hen which are not themselves a grizzle cannot therefore breed a grizzle youngster, and the grizzle youngster I have in the nest cannot have been sired by the Blue w/f cock..

 

I have seen one of my birds, a dark chequer pied, with another form of grizzling, where only part of one or two of her end primaries flights do have a grizzling pattern on them, but it doesn't extend to the whole feather and she is a chequer pied and she's never bred a grizzle either...

 

My question was really aimed at who was (most likely) to be the nest mate's sire, the grizzle cock or the blue w/f cock?

Can't be right I have bred a grizzle and a blue in one nest. Not a Grizzle in the loft and they were all prisoners. The stock were from a chap who had died and all birds were kept prisoner till I had young birds of my own to let out.

Blue base for grizzle and can breed back collours, but i would still pick one of your grizzles for the sire if the young's grizzle typing matched the old uns,  light or dark, pied or straight etc, ?.

The grizzle youngster is a Carbon copy of my yearling grizzle cock's youngsters (paired with Blue bar hen), probably a hen; its nest mate is a Blue chequer, Carbon copy of Blue w/f, body head etc, probably a cock.

 

The old grizzle cock breeds grizzles, but all dark, while this one is mostly white, but will moult out darker.

 

Despite Peterpau's post, still not convinced  Blue w/f is grizzle's sire, though I am fairly confident now that he is sire of the nest mate.
