So, I'm no really sure which topic to post this in, but because I'm concerned about bird diseases, I figured this was close enough. Recently, a homing pigeon decided to move in with our flock. We contacted the American Racing Pigeon Union with the number on the bracelet on his leg and a person called us claiming it, but he never showed up to collect the bird. So fine. We have a pigeon. He gets along with the hens; there's been a little pecking, but they all established the hierarchy pretty quick and now he/she is roosting with the girls. My question is, should I be concerned about any bird diseases that could be transmitted from the pigeon to the girls? Are there other issues I should be concerned about or do we just let them be? Thanks in advance for any thoughts you all have.
