Hi, just wanted to introduce myself. My name is Amie and we've been raising chickens since 2009 when I got 12 of them for a surprise Mother's day present. I was quite surprised since we didn't even have a coop! lol We've had really good luck with them up until yesterday when I went out and found 4 dead. We didn't know what had happened since they showed no injuries, the other 7 were fine and one was even found dead still on the roost like she'd just went to sleep there. Further investigation showed that they had been killed by the buffalo gnats, they are so bad up here right now and I simply didn't realize that they were out there. Lesson learned, believe me. I feel horrible and we've been spraying them and the coop with straight vanilla and it's working so I hope the rest will be ok. If anyone else has any other ideas, I would love to hear them. Thanks!
