So over the past 6 months I have had ridiculous bad luck with anything that nibbles. My pekin bantam flock have been battling mites for about 2 weeks. I just saw a couple of lice on my roo. Plus the neighbours chicken eating cat but thats another story. For the mites I've cleansed their coop, given them ivermectin orally, used pestene powder on them and mixed it with DE for where they dirt bathe. Flipping nightmare and while it's cut down the mites, they're just not leaving completely. I put DE and pestene down almost daily. I'm just wondering how often I can give them ivermectin? I dont eat their eggs so thats not a major concern at this point. I just don't want to kill them with it any tips?
