6-23. 雞隻天生會啄食地面物。若地面上沒有牠們有興趣的物品(飼料、墊料)，牠們會開始啄食其他物質。 *預防─以飼料盤餵料或盡可能將穀物散灑在地面。 *缺乏水和飼料、餵料系統不正確、挑食，需要纖維質。 *家禽飼料中含有很少量的纖維質，因為這是有良好的消化所需。小雞會去尋找較有質感的可食用物，牠們開始啄食地面上的木屑和羽毛，然後彼此啄扯對方的羽毛。 *預防─在飼料中添加纖維質(如苜蓿乾草或其他墊料)。 Chicks naturally peck the ground. If there is nothing of interest lying around (feed, litter), they will start pecking other things. Prevention: feed on feed plates or paper as long as possible, and scattering of grain. Lack of water and feed, feeding structure not right, selective eating, need for fibre. Poultry feed contains very little fibre, which is needed for good digestion. Chicks go in search of edible things that have texture. They start with wood shavings and feathers lying on the ground. Then they pull out each other’s feathers. Prevention: give fibre in the feed, Lucerne hay or extra litter.
