I have seen plenty of chickens enjoy toys, especially if they are kept in a confined area, but most of their enjoyment comes from finding themselves food, because food is the most important thing for their survival. Chickens are not really interested in doing things that do not relate to survival, unless (again) they are confined, and even with that the toys have to have a meaningful reward to be used. I have given mine non-food toys and they kind of stare at it for a bit but then it ends up not getting used at all and they just either poop on it or avoid it, depending on what it is. I put a tambourine in the Gemstone Flock pen once. Jasper stared at it and walked sideways quickly like it was scary. Quartz was wary of it and also walked away. Ruby did not pay any attention to it. Meanwhile I have seen other chickens enjoy toys. I say, if it has some kind of reward to the chickens, get it.
