I just brought home four "retired" hens from a high-yield egg production farm. They are Golden Comets, roughly 14-20 months in age, have tipped beaks and horrendously broken and missing feathers, and were pulled from a barn containing 10,000 other birds. These poor girls don't know how to roost and have clearly had a traumatic past. I want to make sure their introduction to my flock of 8 goes as smoothly as possible while still maintaining the safety of everyone involved. They have been quarantined in my garage for the last three days and have been given layer feed supplemented with fresh veggies/fruit/scrambled eggs/oatmeal. I am looking for any and all suggestions on proper introductions, nutrition, and rehab for these poor girls. I just want to give them the best lives possible and to erase the horrible beginning that they've had to endure.
