Fleas

"The sticktight poultry flea can be a serious pest on chicken farms. Instead of biting a chicken and leaving, as most kinds of fleas would, the female sticktight attaches herself permanently on its comb or wattles. There she has a constant supply of food and lays her lifetime supply of eggs in peace." (p.16)
