Thankyou for your response, So far the bantams seem ok. My Cornish cross roosters are much smaller than the typical ones as they’ve been fed heaps of sprouted foods and I think because their diet is so high in nutrition I’ve been able to prevent them from over eating…..I’ll just keep an eye out...
So it’s ok if a large rooster mates with a bantam? I’ve just found my Cornish cross rooster mounting my pekin Bantsm and am hoping she will be safe as I wanted them all to free range…
