Crowing
I use a stick at least 3 inches wide at the skinniest parts, so they don’t have to curl their feet too much.Some of my large birds like Crevecoeurs, Houdans, and Ameraucanas will use 1 inch by 1 inch, and so will all my bantams (Nankins, d'Uccles, booted bantams).
However, I myself have standardized on 2 inch by 2 inch, since that size is sturdier, available almost everywhere, and lasts longer without breaking or bowing.
