I have 7 chickens and 9 month old ducks. Today when I got home a guinea was hanging out with them. I think she must have came from a mile away. The people down there have a few that wander around their property. She seems healthy, good feathers now signs of illness or injury. She's not tame like my flock but she will get within a few feet of me. She seems to really like the ducks. I don't think the people down the road have a coop or pen for their flock and I haven't seen them in months. She went in the coop with everyone else tonight and seems happy. Think I should catch her and take her back? My mom made a funny comment, "Life guard on duty"!
