Cooper Hawks are the biggest threat that I have here to the flock. They are brazen and will keep trying for a kill. Birds that are in their molt seem smaller and seem to catch the coop's eye more than others. While they aren't large enough to fly off with their kill, they will consume their prey on the ground. They have killed many here, and have tried multiple times in the last few weeks without luck....I also have a good roo that helps alot....cloudy days are their favorite days for prey for whatever their reasons are. Keeping a close eye when the alarm sounds is also a deterrent to their good fortune.
Stay Safe....bigz
