Don't know if anyone posted any of these but here are some toy and treat ideas (none of these are my pictures):
1.Put a head of cabbage in an old onion bag.
Hang the bag somewhere for the birds at head level.
Watch them violently attack the cabbage with no regard for their own safety.
2.Find a plastic ball with holes in it (dog and cat toys like this easy to find)
Stuff the ball with treats like apple, lettuce, peas, etc.
give the ball filled with treats to the chickens
Let them peck at it and chase it. It is the funniest thing, watching a chicken run...
3. Mint has natural cooling abilities.
freeze some in ice cubes along with some fruit if you like
Make sure to add a string in them before they completely freeze.
once done, hang them in the run for a cooling treat when it is hot out.
4.put mealworms in old spice or cheese shakers for easy access
sprinkle little bits at a time to give to your birds
Yes, it is that easy
I am done now.:D
