I am constructing a garden path and want to use gravel with a brick edging but this garden has free ranging chickens in it ! Chickens like scratching up loose surfaces but I am wondering if 20mm gravel will stay in place ! Does anybody have any experience on such matters !?
IME chickens destroy gardens with haste,my old boss frenchy used to keep rare breeds and it never ceased to amaze me how quickly they annihilated a pen before we moved it
but to the original question 20mm should be to big for them to chuck around or swallow
