I am planning on introducing 2 more chickens to my flock. They will be about six weeks old when I get them. Any advice anyone can give me? This will be my first time introducing new chickens. The rest of my flock is about a year old. I have read things about feed. Will I have to keep them seperate until they can eat the feed the rest of my flock is already eating? Is 6 weeks to young to introduce to older hens? I also read to keep them seperate at least for a few weeks to make sure they are not sick. Any help would be great, Thanks!
