I've an idea for a quail toy. Anyone want to try this out? (I got no quails yet!!)
Seed Ball - Get a screw-type hollow ball (like for dogs/cats) & drill 1-3 holes. Fill with seeds a bit smaller than the holes. As the quail peck the seeds that fall out, they'll move the ball & it will drop more seeds. They may run after it (esp if more than one) & get used to the idea that it gives treats.
For best results, use on firm ground with a hula-hoop, large cat ring bottom, or soft home-made ring (if indoors) to keep the ball from getting stuck in a corner.
