I have a turkey and some chickens. I just read online that my chickens can carry something called Blackhead disease and give it to my turkey. It says not to house turkeys and chickens together, however that's not an option for me since I only have one (he'd get lonely), and I know I've been told by plenty of folks in this forum that they too house turkeys and chickens together. Is there a vaccination or something I can give Gobbles?
