Hi , I live in Corona, Ca and we are planning to have 2 hens in our backyard. We are in the process of building the coop but I am starting to get cold feet. We are not suppose to have chickens and now I am afraid of the noise, the smell etc. Do they get diseases? How much care do they need every day? And how much noise can 2 chickens make? Also, some friend told me they are really dirty and nasty... I read this forum and everybody loves their chicken so now am I am torn. Help!
