Bed bugs are known as human parasites, but these bugs can also infest chickens. Bed bugs do not remain permanently on their host, but instead spend most of their time in cracks and crevices of nearby structures traveling to the host at night to feed. They are not usually found in poultry facilities where birds are housed in conventional cages suspended above ground as these facilities offer no harborage for the bugs during the day. However bed bugs can be problematic in furnished cages, cage-free, free-range, and backyard flocks where daytime harborages like nest boxes are available.
