As I just responded to @Huntmaster, I am renovating a barn coop that came with lovely roost branches. We live in cold New England. Don’t have the chicks yet, but soon will have australorp, barred rock, speckled Sussex and americauna. What roost width is appropriate for these breeds in our location? Thanks!For large birds DO NOT use flat side up.
Additionally, it is an incorrect statement that birds will only be able to completely cover their feet on a flat board. Birds can cover their feet just fine on a round branch or similar item, or on the narrow side of a 2x4.
Back to the reason NOT to use flat side for large birds. It can cause problems for them, and I’ve had personal experience with this. As a new chicken owner I put my roost boards flat side up. I purchased a variety of birds, including Black Jersey Giants from a breeder. BJG are the largest chicken breed, and according to the breed standards, only 5 breeds indicate a minimum standard weight for a rooster of 10lbs or more, with BJG standard at 13lbs or more for a rooster (over 1 year of age). Given their large frame and weight, their keel bone rested on the flat side of the roost, this caused friction, and rubbing and my large male (under 1 year, and not fully grown yet) developed a large breast blister that took months to fully heal, in addition to much attention from us. I spoke with the breeder and explained the breast blister, but had not mentioned the roosts (although I had already figured out that the roosts caused the problem). Before I finished the description of the breast blister, the breeder told me that a roost that is too wide will cause this type of issue. We changed all of our roosts to narrow side up, and no problems or Brest blisters since.
You can get away with a wide roost with a smaller bird, as they do not have the size or weight to easily develop a breast blister. But, the wide roosts do not serve any function other than perceived preference.
