I have a batch of Americana chicks that are about 3 months old. In less than a week, three have died. My first thought was overcrowding, or pecking because they have grown for about 3 months. I have separated many of them, and I still lost two. I don't know what is wrong or happening to these birds. I am beginning to wonder if the hatchery I got them from is just a terrible place to get chicks. I had posted about a RedSexLink chick, from the same hatchery, that was nearly bald, very greasy, no tail, and much smaller, it also randomly died before I could get pictures. I have hundreds of chickens, from a couple different hatcheries, and this batch of RSL and Americanas has had more problems than anything else I have owned. My birds have access to the outdoors, large spaces, dirt, plants, and all the good things in nature, we also close our birds in secure coops at night. Any suggestions or ideas would be greatly appreciated.
