Hen shaking head and “opening mouth” adjusting crop?

[red1407]

Looks to me like she’s adjusting her crop. But she does it on and off for a WHILE. Sometimes all morning. She’s done this before so I’m not super concerned bc she resumed to normal…. But wanted to get your alls opinion. Tell me what you think. I have one other chicken who does this, never seen my other two ever do it. Doesn’t seem to be any kind of distress at all. No lethargy or anything.

Looks like she has something in her crop or windpipe that's bothering her.

Our quails and cockatiels do it sometimes

It looks to me that she is adjusting her crop. Mine do this movement every now and then.
