Hi, I'm Lila Jean and my husband and I live on a little hobby farm in Cleveland, Ga with 21 chickens and three rabbits. We've had backyard chickens for around 14 years but now find ourselves in what, to me, is a very stressful situation. In the last 2-3 months we've had three fox attacks and lost five hens. We've always allowed them to free range all day and now we're having to leave them in their run most of the day until I can be out in the yard the last couple hours of the day with them. Not only are they sad but worms and mites are becoming a big problem. Before when we've had to worm them, our vet recommended ivermectin but it looks like from posts I'm seeing, that may not be the best option now? I'm so concerned because I desperately want to let them out for their best health but also don't want to lose them all, one by one to foxes. I can hardly think straight and am praying someone can give me some clear advice. I greatly appreciate anyone who takes the time to read all of that and replies.
