Hi, I just got two new chickens, a rooster, and another hen. They are close to the same age as mine and I bought them from a breeder. Unfortunately, the breeder didn't say anything about how to introduce them or anything. So I immediately added them to my flock. I observed them awhile and saw that my hens were telling them who was boss by pecking at them and running them around. So luckily I looked online to see how to introduce them without them getting injured. I'm glad that I saw that I should quarantine them first - so I took them out and put them in a pen in the garage. I also cleaned my coop - worrying that I may have introduced an illness without knowing. I just cleaned out the old hay and put in new hay. Do I need to do anything else to insure that my chickens don't catch anything from these new ones? Please let me know if I should do more. The new chickens were probably with mine for about 30 minutes. It wasn't long. Thanks.
