I am looking into starting to raise chickens (maybe 4 to start) and I want to do this as a test run to make sure this will be a fit for my household. I don't want to go out and build a big coop with a lot of expense and find out there are issues with my neighborhood etc. I would like to build a smaller coop in my garage where I have an old dog door to the outside where I can put a run on the outside. If it works out I would either move the coop to the outside or build a bigger permanent coop in a better area with a bigger run depending on the number of chickens we end up having. I don't see an issue with the set up except for two things, One that the garage is kind of dark so putting a window in the coop would allow a little light but not a lot and second would be the ventilation issue. Would that still be okay for the chickens or would I need to put an artificial light within the coop and some sort of ventilation in. I know winter time artificial lighting helps with egg production and over all health of the chickens.
Anything to help with this thought would be greatly appreciated.
