Thanks for feedback. Will take a lot of work and time. Obviously he must be a cross bred Brown Leghorn too since he has the same or similar leg colour my dorkings have.
I have 3 silver grey Dorking pullets. But no rooster. I have a brown leghorn rooster which I want to breed with them. I just have the following questions.
How would the offspring look like?
Would any chicks have 5 toes?
Otherwise how long or how many generations would it take to breed back to...
