i crossed a light sussex roo with a white rock- hens are all white with some very slight smokiness in their neck feathers and one or two has an odd black feather. is white dominant? also, if i breed my light sussex roo to rhode island red hens, will this produce a sex linked chick? or no? i have seen some conflicting sex link info and i'm wondering what the deal is since i don't 'get' the whole genetics thing yet.
