Actually it's very humane. Inbreeding does not have the effects in chickens that it does in mammals. I wrote a whole article about it if you would like to read it. https://www.backyardchickens.com/articles/inbreeding-not-as-bad-as-it-may-seem.74335/If the f3 female was related to the p1 male, do not breed together- that's inbreeding and can cause health issues- also it's not humane.
thank you,I'm a little confused with your question
If the f3 female was related to the p1 male, do not breed together- that's inbreeding and can cause health issues- also it's not humane.
If you hybridize a jungle fowl x a domestic bird, you are not creating red jungle fowl- you are creating a jungle fowl HYBRID which has less jungle fowl genetics.
Even though your rooster might look like a red junglefowl, it is not a pure red junglefowl. So, your backcrossings will produce chickens that look like your rooster. Like what the others have said, if you had a pure rjf, you cannot produce more pure rjf by crossing with a chicken. The only thing you'll get are chickens that look like rjf.thank you,
actually i had crossed rjf male with enghlish game female as mentioned in picture, had got a female with almost 70 % similar phenotypic features like rjf female, now i want a generation which is similar more to rjf, i want flight character in final generation, and disease resistance, so now want back cross of f2 female with p1 , may i will get more similarities in BC 1 to rjf or nor, i want rjf acutaly
