Ectoparasites (e.g. lice & mites) are often a problem for small flock producers. These insects are extremely small (about the size of a pin head) and difficult to detect unless one knows how and where to look for these pests. Even though they are very small and not easily noticed, they can cause problems for caretakers as well as the birds themselves. Heavily infested flocks can suffer substantial economic losses as a result of reductions in egg production, reduced weight gains, lower hatchabili...ty, increased feed costs and increased mortality. Poultry workers may experience the uncomfortable conditions of numerous bites and skin rashes.
