I have lost 2 hens this month. I only have one left. She appears to be fine. She was the biggest one and seems quite strong. There is no appearance of mites of any kind. Is there something I should do to protect my last girl? This is my first time with chickens and I am unfamiliar with medications. I also don't know how well my last bird is going to do on her own. Won't she be lonely? I would like to get her some company. I looked at Meyers and they ship pullets ( I do not have the equipment for chicks). Has anyone had any experience with them? Also, because there is only one bird will the pecking order adjustments still take place? Do I have to gradually introduce the birds? Thank You!
