A poster on my knitting site rescued a pigeon when it fell out of a nest and was abandoned by its Mom. She named her Chicken and now she realizes that Chicken is too domesticated and cannot be let out into the wild. Chicken is an active bird who enjoys throwing around this poster's yarn and when I suggested toys, she asked me what toys a pigeon would like. She tried some cat toys but Chicken wasn't interested in them. For those with doves, what kind of toys should I suggest? Thanks in advance.
