Orpington cross sex links?

[ItsONuh]

These chicks are all from an orpington (buff+lavender) roo over cream legbar hens. In theory they should be sex linked... what are the 3 black ones then versus the blonde chipmunk that just hatched? Thanks in advance!

All the birds with headspots are definitely cockerels The barring gene is located on the Z chromosome and females are ZW and males ZZ. Females receive a Z only from their father. Males receive a Z from each parent. This is why barring is only passed to cockerels The other chick should theoretically be a pullet if she has no headspot which indicates barring

I guess I'm just confused because I wasn't expecting black chicks from this mix but maybe that's part of the barring? Would it then really be as simple as "chipmunk chicks are pullets & black barred are cockerels"? Couldn't possibly be that easy..

The black is because they are split to lavender.

Lavender is a modifier of black.

Thanks. So to further solidify, with this mix the ones that come out black- the females would be solid black with no head spot. Chipmunk females will have a dark V on the heads while males have lighter heads. I think I'm understanding this better now

I don't understand the sexing of chipmunk chicks myself.

But the headspot means barred and any non-barred rooster X barred hens produces barred sexlinks with males barred and females not.

Sorry to jump on this thread but it confuses me too. These lighter ones are from Whiting True Green hen X Lavender Orpington roo. In the past I’ve only hatched out darker chicks with red heads, so these took me off guard. Could they be sexed by these markings too. Thank you for any responses.
