Hi, I am in England and have a breeding pair of Jubilee Orpington Bantams, however they are very small compared to my other Orpington Bantams. With the mix of genes in the Jubilee how would I go about improving the size?. I did think of breeding the cockerel with a Large Fowl Jubilee? or would it work using a Mottled hen and then breeding the offspring back? Any views would be appreciated.
