To breed purebred chickens you have to have a rooster and a hen of the same breed. Example, RIR x RIR will give you 100% RIR offspring. To make a mixed you don’t have to isolate a rooster, it just means your breeding two different breed together. Mixing two crosses of the same cross dose not make the offspring pure. Example. RIR Cemanis mix x RIR Cemanis mix will just give you more mixed chicks.
Yeah, i know that, that's why i'll put one rooster, with many hens of different breeds AND the same breed together, because i know where they nest and brood, and both eggs in incubator and under the hens will be marked with pencil, noting the details of the parents, date and numbers according to which one is laid first. After, a week, I'll remove the rooster, and take in another rooster to accommodate. Once the eggs hatched, I'll seperate it immediately from the parents into brooding boxes where ilabel them with leg bands. The undesired ones will not be labelled and raise for its meat instead, and be isolated from purebreds, layers, and broilers. So does hybrids, to be isolated from aforementioned.
So, for example, 3 hens, RIR, WL, fayoumi and cemani in a pen, and i left fayoumi roo in it, the results would be, FxRIR, FxWL, Purebred Fayoumi, FxCemani. Each within their stationed nests. Then i move the hatchlings to my brood box, and label them, and before that, switching Fayoumi roo, to RIR roo, so in the coming time the hens lay again, it'll be Purebred RIR, RSL, RIRxF, and RIRxCemani. I'll repeat with different roosters this same method.
Solid?
