So Thanksgiving day we had a 14 week Silkie chick disappear except for a handful of feathers. I'm pretty sure a hawk or other bird grabbed it and took off. We had our run as just a 3 foot high fence and despite having our girls out in this type of run all summer, now that the garden is done for the year and much less ground cover, we lost a chick. Anyways, so the next day (after locking the girls all up in their coop the rest of the day), I proceeded to completely enclose their run.. The next day after it was all complete (27th) we came home and saw the following... So we are making the assumption that this hawk is our murder... and are super thankful we had just finished our enclosed run so we didnt end up losing anymore of our silkies.
