Asking one more time what kind of birds are they? I have never met a mean cockatiel, but I am sure there are some. But when you said one destroyed a toy in a day, it sounds more like a bigger parrot. I give my cockatoo a box with smaller boxes filled with treats in it. He spends a day destroying the box and it did not cost me anything other than the treats or peanuts etc I put in the small boxes. There are on line toy making groups where you learn to make your own toys which are much cheaper than bought ones. You can email me at
[email protected] and I will send you info on groups that will help you and keep costs down on food and toys. Take care.
