using a Legbar rooster over a Black hen WILL NOT produce Sexlinks...... thats that... but Using a Legbar rooster over a Welsummer hen will produce Autosexing chicks....Why? you see the males will show the large headspot and the hens will either lack the headspot or have a very faint one, making that an Autosexing cross? why? because welsummers and legbars both have e+ wildtype and the cross will be e+/e+ B/- for females and e+/e+ B/b+ for males

whill the Headspot is a Dead give a way that the chick is going to be Barred, its not so clear on the sex of the chick as the father was barred and mother black.. the chick can be male or female(50%) and I would say both chicks are females... would love to see the chicks in a few weeks from now

yest typical ER/e+ I/i+ birds....you see ER is dominant over e+ and they are dominant white due to the gene found on the buff laced parent.. why they are not laced? well thats because you need homozygosity on the following genes.. Db, Ml, Pg and Co..... since this is not the case the birds are not completely laced

Would the Welsummer need to be a Silver Welsummer for the Sexlink to work?

cream legbar rooster crossed with silver welsummer will produce Autosexing and Sexlinked chicks both at the same time.... the males will have large headspot and a lighter silverish chick down. the females will lack headspot or have a very faint one and their chick color down will be darker.. cream legbar rooster crossed with gold based Welsummer will produce autosexing chicks... the males with large headspot on their heads, the females will lack the headspot and will have a clearly defined chipmunk stirping on their head maybe with a faint headspot but the headstrip will be well defined..

Quote: no the mother was not just black in my case . i guess i can only speak for mine but a barred bird crossed with a barred bird the males will have a head spot and females wont is this wrong. I got yelled at and had many aggressive debaters pound this in my head a year ago.. Also since you know genetics is the barring in a barred Cochin silver based color.

maybe both female due to head spot being light

wildtype is the Only e allele were the headspot on the females is either absent or very faint.. check Rhodebard chicks, welbar chicks also, 99% of females lack the headspot, only on legbars you see a very faint one in like 40% of the females.. BUT in other e alleles like Extended Black(for example Barred Rocks) the females have a headspot, but its maller than the males in the Allele ER birchen(for example Golden Cuckoo Marans) the females have a headspot aswell but its smaller and the Males are alot lighter than females, their chick down is affected by double dose of Barring. in the Allele of eb(crele Penedesenca, Wybars) the females also have a small headspot but they are dark brown and Males have a larger undefined heaspot and are much lighter than females... check my Thread on this subject...examples with pics.. take a look at the Golden cuckoo maran chicks http://www.the-coop.org/forums/ubbthreads.php?ubb=showflat&Number=105920&page=all

Just Wow! I really wish that I had your knowledge level of chicken genetics. Would you have any recommendations/links where one could improve their knowledge level in this subject matter? There is so much to learn which is a great thing.
