Our chicken coop is very short (up to my knees and I'm 5'3). Our chickens like to sit on top and it gets very dirty and looks pretty awful and I don't want my fancy babies standing on that and it gets in their foot feathers and is a nasty mess. How to keep them off??? any ideas? You know those mats they sometimes put under computer chairs and how they have that spikey side? well maybe putting one upside down on there would work. i dont want them to jump up there without knowing and really hurt their feet though. maybe set each on up there gently so they know what it is? please advise
