A healthy varied diet and hygienic conditions will help to keep your chickens in good health.
In the peak of fitness, chickens should be bright eyed and alert. They will have clean legs, feet and bottoms, as well as healthy wattles. Chickens, like all birds, are very good at hiding illness so owners should watch them carefully in order to recognise any changes in their normal behaviour.
Using mite and louse powders will help you avoid the most common problems. Natural alternatives are also available that will help with parasite control and maintain chicken vitality.
As with all pets, if you are concerned about any aspect of their health you should consult an appropriate vet.
