How many of these breeder cages are you building? You might want to think about attaching your feeders on the outside. If they are on the inside, the birds will get in them and kick the food out. They will waste more than they eat. I have a bucket feeder that has a very narrow trough. The birds can't get in it but they still figure out a way to kick alot of the food out. Plus another advantage is that it will keep you from having to open up the cage to clean and fill the feeders. You can also order those waterers that attach to a 2 liter coke bottle. They are also fed from the outside so you don't have to go through the cage to change the water. Just some ideas that might make it easier on you.
Those are cool what is the wire that you used and how did you put it together? or did you order it?
The glory of friendship is not the outstretched hand, nor the kindly smile, nor the joy of companionship; it is the spiritual inspiration that comes to one when you discover that someone else believes in you and is willing to trust you with a friendship. -Ralph Waldo Emerson
