I lost my first 4 sex linked to faulty tractor design and likely a raccoon. Raising my numbers to 9, a new coop and run, all was well. With a floored coop, lights, and being next to the house, all seemed well. So as long as we were out adding features to the coop I let the girls free-range . They really seem afraid of tools. --At one of my 'check what the little girls were doing' I counted 5 under the thorn bushes, and assumed the 6th was in the bushes someplace. As you may guess 5 of 6 of the little girls made it home and there has not been a trace of Dottie. The 3 bigger girls were in another part of the yard and are fine. ---I wonder if my problem could be solved by a Roo? I have avoided a Rooster to keep quiet on my yard, and out of consideration of the neighbors in this semi-rural area. The idea of a rooster proctecting the flock, and maybe keeping them grouped seems attractive. So would a big old roo help?
