So, I know that Cedar, is supposed to be really bad for birds respiratory systems, but I found a natural mite and lice repellent and the main ingredient is cedar-tree oil. I don't plan on spraying my chickens and ducks directly with it. But is it safe to use in and around the coop. I checked with the actual company and they said that it's all natural and safe, but birds do have sensitive respiratory systems, and that I should just air out the area after I use it. Would you think it's safe as long as I put them out in the pen and open the windows to let the coop air out afterword. I checked all the other ingredients and they would be fine, it's just the cedar oil I'm unsure of. Thanks!
