Get some pellets if not already using them soak them in water to a mush, put in a empty type ketchup or mustard bottle the type with a tip then you can squirt in some mush once a day. I have done this on occasion in the past but if fully feathered under its wings it should be eating on its own.
It was one of those deals I had to jump on!
The door at the bottom is hinged also inside are three clean out trays under each box, it is also wired with lights and an electrical outlet also. The only bad thing is the sliding trap doors they are made of layered cheap wood and buckle in wet...
I gave 200 bucks for the box, birds, training cage and a few odds and ends.
The fellow said he was tired of feeding hawks but I think there was more to the story as the box looked like it was not in place long, and he also lived in a VERY upscale community.
