We are first time chicken owners, and currently have four, four-week-old pullets. They are doing fabulously, and I am thinking about adding another pullet of the same age from a nearby farm. We got our original girls from an online hatchery, so they have been very healthy. What steps would I need to take to ensure this new chick is healthy? Other than taking a very close look when I go to pick it up, how long, if at all, wouldI need to keep it separate from the other girls? If it's going to be a huge pain in the butt, I likely won't go ahead with it. I don't want to put my girls in danger, but I don't want to have to segregate one poor little girl for weeks on end.
