Amy Murillo, Ph.D., with the University of California, identifies three ectoparasites to look for in flocks. She also shares her expertise for controlling parasite populations:
- Northern fowl mites
- Lice
- Sticktight fleas

Cleanliness and biosecurity are the first lines of defense against parasites in flocks. Clean the chicken house regularly, and seal any cracks or crevices to limit rodent access. Inspect birds regularly, ideally monthly, and monitor parasite populations. Preferably, examine all birds, but if it is a large flock or it is too difficult to catch all the birds, focus on males, birds that look ill, or birds with damaged or commercially trimmed beaks.
