Cause– This disease, which is now though to be more prevalent in pigeons than once suspected, is caused by gram negative bacteria’s which can invade our lofts through infected dust particles, rodent droppings, and trough infected pigeon droppings coming into contact with eggs in the nest. Infected adult pigeons will emit the bacteria throughout a pigeon loft.
Symptoms – Since the E. coli bacteria can manifest themselves in any part of the pigeon’s body, symptoms can be diverse.
Most often young will die in the nest, adult birds will
become listless and lose weight, and their droppings will become loose, mucous, and greenish-yellow in appearance. Sometimes the droppings will have a foul odor. Occasionally some birds may have nasal discharges and respiratory problems associated with this disease.
Prevention – Maintaining good loft hygiene and keeping rodents away from feed and water are very important. Also keeping dust and ammonia levels down will help to control any outbreaks.
