Hi all, I'm so frustrated. Seems every few months I check my flock to find lice and or mites again. I've tried it all, from the holistic approach to full blown chemical warfare....seems I'm always fighting it. Any advice or tips to keep the bugs at bay is greatly appreciated! I rarely if ever add new birds to my flock, and if I do, I make sure there bug free. I use only pine shavings and change the litter in my coops regularly... Thanks!!
