Welcome to this website. If the bird can mate then the eggs will hatch, But I am not sure of what the purpose of crossing Cornish wite gamebird. The outcome is a mixed, not game enough, and not showable as cornish.
since we have gamebirds i want to try to imporve their meat quality even though they taste delicious their meat si still small and since my 1st flock that i personally i want to cross my cornish and also i want to have an offspring that has more life span and healthy since our gamebirds free range and gave strong immune system even though we dont give them supplements and vitamins.
