I rescued these chickens from a place that raises chickens for meat. These were the "runts" and were just going to be killed. My in laws took all 40 runts and are going to raise them up bigger for butchering. But when I saw how sad and dirty they were (they were clearly in close quarters) I decided to try and give two of them a chance to be laying hens. We have the space. Right now they are in a smaller coop clear across the yard from our other chickens. What kinds of diseases do I need to look for? Can I bathe them? What symptoms do I need to worry about? I am still a newbie chicken owner (2 months). Thanks!
