Possum chicken farm
Chirping
The person who gave him to me wasn't positive of his breed, though he looks like a silver wyandotte or seabright?Mature size is breed dependent too; a Jersey Giant may grow for another year, for example!
My Chantecler cockerels usually add another 25% (or more) after six months of age, and I don't consider any six month old cockerel anywhere near adulthood.
I don't often weigh the bantams, except to say that they do grow a bit more too.
