Also, please keep the cage clean...very important and fresh water always! Birds are pretty messy.
Yes, their water can get messy within a few minutes! I use to use water bottles and food dispensing cups. I stopped when I lost Cheeko because I have a nagging feeling that she stuffed seeds and other things in her bottle and couldn't get water. I didn't notice because her water bottle seemed like it was going down and I thought she was getting water...I'm thinking that is what caused her kidney failure. Not sure because the Dr said she could have been born with it and it just took time for it to develop.
I think I will go back to a water bottle for kitto but I will be making sure his water bottle is clear of things every single day. So if you do go the water bottle way, make sure he's getting water. Water bottles are less messy and don't become contaminated as easily.
My African Grey LOVES to take baths...I will fill up a sink with about 2 inches of water (luke warm) and he'll have a ball. Though, slowly introduce this to your bird if you choose this way. I got my bird loving baths by starting out with a bowl first...then I gradually allowed him to "test" the water. This will keep them well conditioned and their feathers in great shape.
