I understand that house chickens aren't for everyone, but people who choose to share their homes with these amazing birds will never regret it. Personally, I have two chickens in my house. I have a Japanese bantam hen and a White sultan rooster. The two of them get along great!
I have read most of the posts regarding indoor chickens, and most of them say that it won't work or that they would be messy. I am setting the record straight. Chickens make awesome pets indoors, but size does matter. The smaller the chicken the better. In regards to the dust issue, one chicken doesn't cause too much of a problem. We had 8 chickens in our house at one time, but they moved outside in the spring.
Requirements for keeping an indoor chicken:
You have to be okay with noise. (roosters only)
You have to have an outdoor space that is fenced in. (this is for letting your bird out when the weather is nice)
You have to be willing to give the time for cleaning the cage and spending time with your bird.
You need a container that can be used as an indoor coop at night.
You will need to be willing to bring your chicken with you on vacation or have a house sitter take care of it.
Now, with all this being said, living with a chicken is one of the best decisions that I have ever made. When you interact with a chicken on a daily basis, you get to know their personality and learn to see the world through a chicken's eyes. I will say it again, living with a chicken is not for everyone, but those who choose this route will never regret it.
