I'm so sorry to hear about your little one and his injury. I agree with your assessment above. I have not had that experience myself but I think he will continue to have a hard time.
I currently cannot directly post pics to this forum due to device incompatibility either. LOL If you would like to see the pics I've posted in the past you can see those under ' IMAGES' on my profile page. I started with chickens also. :-)
