Mine climbed out the top too! Thought I was losing my mind when I found the locked and empty cage. I put a board with weights on top to end the escapes.Tried that. Also put ice underneath.
The broody jail is a dog crate that I turned upside down so that the smaller wiring is under her. The crate has rather large openings where the plastic pan would go under a dog. She managed to squeeze out of the holes at the top to get to the nest. She's a big ol Brahma, and she somehow flew/climbed up and squeezed through a 4 inch opening to get back to a nest. No clue how. Nothing in there to really climb on because her food and water are in small containers at the bottom of the crate.
I am so sorry about your stressful situation. It can be frustrating when just. Won’t. Go. Smoothly. Agree with others about picking up and placing in front of food. For weight gain a little bit of fish (mackerel or bone in salmon) is full of nutrients. Good luck and hang in there
