Okay so I have recently been researching chickens diseases and everything else before I purchase my little chicks so I live in the city and have a pretty big back yard that is split into 2 parts and 1 part I want to use for chickens and bunnies but I have been reading this histoplasmosis or however its spelled. My question is .... even if I clean the coop etc.. I want to let my chickens roam free during the day time in the 1 part of my yard. I have been reading it is chicken poo is good for your yard? But at the same time I was wondering if I would be at risk of catching that histoplasmosis doing things like raking mowing etc.. and how would I prevent it? I really want chickens but i'm not going to lie im quite afraid of catching something from them. Please let me know if anyone just lets there chickens run around and if they have heard or know of anyone catching an illness from letting them do so.
