I've just received my order of 31 (that's right!) French guineas. Fives days old today and heathy. How long do they need to be on medicated starter (turkey or game bird)? I have 25 two month old barred rocks in my run now. How old should the meets be before I introduce them to the chickens? I want them to roost together. I'm keeping them in the basement of my house right now. After two weeks I'll move them to an enclosure in my mini barn. All suggestions welcome.
