Getting a Roosting Pole

Chickens love to roost and this is them enjoying the new roosting pole. When they are perched up on the pole it is mainly when they are sleeping. I have a picture of them being put on the pole. It is a picture of 1 and then 2 and then 3 and so on until I think 9 are on the pole. When I took the picture with 10 one jumped off. If I could of got all 10 I was going to make a counting book.
