The Roost---Dimensions and Design

I set up a 2 X 4 for mine. I'm a chicken newbie though, so take that for what it is worth.

 

I used tree branches about 2" in diameter in the run and a 2X2 in the coop.

 

Oh, and Capebird - that is one big chicken in your avatar

 

We used 2x4 boards. All are very comfortable.

 

we have a 2" tree limb in the run 2x4 turned edge up rounded down .

 

Why not try some of each? See what they like. Just remember, they will go to which ever one is highest so try to have all at the same height and similarly protected (mine all like to be in the corners of the coop.) They will use all of the ones you mentioned if it is all that is available.

 

I use 2" x 3" on edge first run is set at 48" above floor so they have to fly up to roost. Second and third run are set at 12" rise and 12" run apart. The 2 x 3 boards are notched into a 2" x 6" stringer set at 45 degrees. If you would like photographs I can post them tomorrow.

 

I have a 2x4 (flat side up) and they use it fine.

I'm even thinking about getting a 2x6 for my next coop!

 

2x2 for us and 4 ladies use it just fine. It looks like mine are training for the balance beam as they walk across it from one end to the other. It doesn't take much to amuze me!!! Have fun with the chickens.
