New to this! I have a broiler rooster who is currently 16 months old weighing almost 5kgs, I had him bred to my native hens which are 1/3 his size and now has his chicks to 1 month old. He was the runt of the batch resulting for him to be the only one I hadn't butchered, he was once at 1.5kg at 6 months and I prioritized him resulting in his comeback.
