How big is the tracker?I would like to put a tracker on it so if they get out again I can find them. We have 15 acres so when they get out its impossible to find them.
Maybe you could put a strap around the base of each wing, so the chicken wears the tracker like a backpack.
(Of course there is always the chance of the chicken getting it tangled on something and being trapped, and there is also a chance of the chicken losing it. That would be true with almost anything you attach to a chicken.)
