I have had chickens for 1 year & today was my first real predator attack. We have a lot of Ravens, Eagles, Owls & Hawks in our neighborhood. The Ravens were always the least of my concern but today that all changed. I had one Raven that went after my chickens 5 times today. As far as I know this is the first time this has happened. Luckily I was working from home today & heard the hens making a terrible noise. By the time I got outside there were feathers everywhere but she was uninjured. The aerial attack continued off & on today. I do not have a covered run for the girls but the run is filled with fruit trees & this has always given me some sense of security. I do not have time until this weekend to build anything substantial so they will need to hang out in the coop & the small space (4 x 5) underneath while I am at work. There are only 4 hens so hopefully they can cope with it till I get home to let them out while I can supervise. Has anyone heard of Ravens attacking chickens before or is this just a Rouge Raven? Thanks!
