Hello, I'm new to this site and hope I'm in the right place to get a little help...My daughter has 15 days before she shows her Cornish X at our local County Fair. The birds wattle and Combs aren't very red. Is there something we can feed them to get the desired color? Last year was our first year raising these birds and she fared well. She got a purple ribbon in the meat category. This year her birds aren't looking so promising so any help would be greatly appreciated.
