Yesterday my copperblack marans rooster got on another colour than expected , he jumped on a few Sussex breeds and left it by only these white ones with black neck instead of his breed hen . I have no idea about hatching and try to get myself as much info I can get altough I'm not even sure these hatchlings should be born due the fact I've read about misformings , such as that has to be the same etc . Is it a known breed that comes out of this or is it a ' mixed chicken ' only ? would they look like their mother ( white ) or do they become black / copper or even both ? what is the sexlink in fact ? who has most influence on the youngsters ? I did see a brown hen having brown - white chicks due a sussex rooster but these colours marans vs white sussex is what I can't find online either ? are the hatchlings going to be able to grow as should ?
