I have 6 chicks that are almost three weeks old. They are currently inside in a comfy brooder. Today I bought a 1yr old buff Cochin (oh my, she is the calmest sweetest thing!). I brought her home, gave her a bath, nursed a wound she had on her back and discovered she has mites. I put her in the coop/run outside. How do I go about treating her for mites? There are pine shaving in the run, will mites live in the shavings? And how should I introduce the new hen to my babies? The babies usually go into the run on days that are warm (I'm in Georgia so right now the weather is great) but I don't want my chicks to get mites. I also feel sorry for my sweet new hen that's all by herself in the run. What do I do?
