Hello, I noticed, that my favourite hen-Dolly (who's a Cochin) seems to not be feeling well. Several feathers are missing from her head including her tail, I think that the other hens are picking on her. When I look @ her face she just doesn't look too chipper. What we're planning on doing tomorrow is taking her & another hen (for company) who's picked on a little too. Putting them in a secluded area, giving them vitamins & Yogurt etc. Until they look a little better. My question is: Does anyone have a reccomendation or an opinion on something called AVIA CHARGE 2000. Thank you in advance for any info!
