Yes. When kept in a flock together, chickens and guineas will indeed interbreed occasionally. Sometimes the result is a fertile egg. The survival rate in these hybrids is higher if the female is guinea and fertilized by the rooster. In this case the incubation period for the resulting egg is 25-26 days. There is a lower probability of survival for those hens who mate with the guinea cock in which case incubation is usually 21-22 days.
yes.
Yes, you need a male chicken (cock or cockerel) to have chicks with your female chickens (hen). However, you do not need a cockerel to produce eggs, as a hen will produce these nearly every day!
