Certain diets also require the use of grit, tiny rocks such as pieces of granite, in the feed. Grit aids in digestion by grinding food as it passes through the gizzard. [2] [5] [6] Grit is not needed if commercial feed is used. [5] Calcium iodate is used as supplement of iodine. The feed must remain clean and dry; [2] contaminated feed can ...

On average, a chicken lays one egg a day for a number of days (a "clutch"), then does not lay for one or more days, then lays another clutch.

[22] In the traditional system of transhumance , people and livestock moved seasonally between fixed summer and winter pastures; in montane regions the ...
