Thanks for the link Alex,By Auto sexing breeds I meant these can be sexed at day 1.The chicks being lighter or darker than the opposite sex.This can be rhodebars,legbars etc.I was wondering if anyone kept these breeds in the USA.
Thankyou for the link there was info on there regarding Auto sexing breeds which can be sex at day 1.
Sex linked breeds do not breeds true.Auto sexed birds do.The site was known to me being in the UK.
