Black Grouse Chicks Getting Bigger

I did promise you a video of my Black Grouse chicks now they are bigger.  Taking this video was a challenge so it is very short. Mother hen got very annoyed when I tried to put the camera in to take a close up. Then the camera got covered in poop, so I had to get a short top view shot. This is not speeded up these birds at this age at feeding time are crazy birds,. But as adults they are lovely calm birds.
