Broken beak patent

Chickens peck hair or anus because they lack some trace elements. You can add some trace elements to the feed, which are sold in feed sales points or animal husbandry and veterinary stations all over the country, or break the beak of chickens.

As for chickens pecking at chickens, it is an instinct for roosters to be aggressive. The solution is to put an eye patch on the chicken. The specific principle is to cover one eye of the chicken so that it can only see with one eye, so that it will not fight.
