I have a purebred Light Sussex cockerel running with four Isa browns and two purebred Black Minorca's.
If the LS ever gets round to servicing the Minorca's,(he tends to be knocking seven bells out of the ISA's at the mo) any idea of what the resultant hatchlings would resemble and what colour eggs would they lay?

Minorcas lay large white eggs and LS lay light brown/cream eggs!

Also would the chicks be sex linked?

No idea but I have the same thing in one of my pens, ie LS cock with 2 Minorca hens (and a load of others too). I don't intend hatching any eggs from the Minorcas (well I don't think I will); they are just in the pen for somewhere to put them. It's all up to whichever gene is dominant, the white egg laying gene or the brown/tinted one. I don't know much about genetics but maybe someone else will be able to come up with something, in layman's terms that we can all understand please!!!!

Our light sussex cockerel(Gandalf) has produced mini imitations of himself from our 4 hybrids a bluebelle, black rock and brown type hens(rhode island red cross?) You can't tell the difference between the pure light sussex chicks and his own cross bred ones. We got one magpie colour though - black with white neck from the black rock hen crossed with him - nasty tempered thing it is, just like her!

Being a Geordie, magpie coloured hens sound good!

[Bramble-Poultry]

brown is a dominant egg colour, therefore if you put a LS cock to a minorca hen, you should get light brown, possibly dark cream coloured eggs.

Think of the wernlas olive - an olive laying bird. Its genetics (being cream legbar based) predispose it to lay a blue egg, but the brown gene from the cobar (cochin x barred rock) is overlaid on top as the last colour fix and gives the egg an olive tint.

Thats my prediction anyways!

I don't think the chicks would be 'sex-linked'. Most such crosses use a darker coloured cockerel on light coloured hens, and the girls have Daddy's colouring.....
