A couple of days ago we got rid of a "hen" that turned out to be a roo and now want to add a young pullet (about the same age) to the batch. We only have 2 now - BR and Ancona - and they are friendly, easy-going young ladies (about 3 months old). Do I have to quarantine the new one? If so, for how long and is it just to insure that she is not sick? My plan is to let them all free-range together at first introduction and then to put her into the hen house at night after the others have been in there for a while. Is that the best way to go about it? Thanks.
