My BPR is just about 20 weeks. The last few days I have heard a strange noise scratching noise and went out to investigate. She is jumping up against the inside wall of the coop. It's the wall with 2 windows and the nest boxes below. On the opposite wall is the perch but it's not a window height. Is she trying to look out the window? The pop door is open so she could go in & out freely. I'm puzzled and am worried she might hurt herself. Any suggestions or ideas as to why she is doing this??
