I'm new here and I need some advice and information. What I believe to be a hen made it's way into my back yard and doesn't want to leave. He's very sweet, follows me around all day while I do yard work. Falls asleep on my lap and likes to perch on my hand. If anyone can help with approximate age, health, breed really any information would be helpful. I can't afford to take it to the vet. I built it a coop and I'm doing my best to keep it healthy and comfortable.
