I want get some chickens, my local municipality does classify them as allowable pets. There are no restrictions for 'small' groups of chickens.
Like any pet there are a lot of considerations when choosing what type of pet to get, but chickens seem desirable, as in addition to their other attributes you get fresh eggs to eat. While it may or may not make any health difference I have decided to include a rooster, so I can have fertilized eggs. I won't be breeding any chickens just harvesting their eggs.
I have chosen the Rhode Island Red for it's appropriateness for the home environment and it's attractive color. From the question How much dominance is expected from two male chickens of different breeds? I learned that some consideration should go into the hen/rooster ratio but am not sure what the ratio should be or how to determine it.
