I am new to chickens. I was in the veterinary field for 9 years before my children were born and have been out of that field for almost 7years now. It amazes me at how fast I have forgotten a lot of medical things that used to be second nature response. My question is how chicks get coccidia when they have been in a brooder box and not grazing in areas where it is found i.e. mud puddles, dirt? From what I remember about mammals getting coccidia it almost always was in some sort of infected area, such as a boarding kennel where other dogs had defecated shedding the coccidia, or a kitten coming from a cattery, a drink from a muddy hole somewhere, etc. I guess I want to know if it is something I really should be concerned about until they are moved outside and exposed. Thanks for any responses!!
