Yesterday our flock was visited by a not-so-friendly K-9. He took out half of our flock, two ducks, a guinea and ripped our rooster apart (rooster was still alive, but in total shock so we had to put him down). We had about 25 birds and we are planning to increase to 100 by the end of the year..This has set us back a little bit and really broken our hearts. We feel like we failed our birds, but we just haven't had predator issues on our free range system in the past because we have a dog who guards pretty well. Our dog was just much smaller than the one who attacked so she couldn't help this time. We plan to build a much larger chicken house this weekend with a 1/2 acre of portable electric poultry netting to keep the dogs out. Hopefully we will be able to prevent this from happening again...
