We have a current flock of 5 hens, 1 roo. This coming spring we have on order 5 more bantams and 10 more layers. I know there are different opinions about quarentine and such but am wondering at what age folks have found bext to add a bunch (15) new girls to a small flock. Also, just to make it a bit more challenging, I am planning to move my little flock out of the run and coop they have been in from the start. I am thinking I should relocate the existing hens for awhile before introducing the pullets. The new coop is two levels, the bottom being an enclosed run underneath the "living" quarters and nest boxes. Should I keep them confined to the new coop for a certian amount of time before I let them out to range? The old coop set up is remaining in place to be used for other things so I am concerned they will try to go there instead of the new one. Since one of my dogs is a chicken muncher it is ESSENTIAL that my ladies come a running when its time to go back into the run so I can lock them up (they are so good now I just have to call and they come running and strut straight into the run). Any opinions?
