I know many people have different opinions when it comes to roosts whether it be rounded perches or 2x4. But my question is, which roost is healthiest for the chicken to lay on. I recently saw an article that was very hard to understand because of the wording used in it that said that one or the other could harm the chickens front bones near the breast whatever you call it? Anyway. What roost is the healthiest that will keep your hen living and comfortable for many years?
