Thank you all for the links! I'm working my way through them now. I'm sure you all know how when you open up a thread to read it leads you to another, and another, and another, it's addicting!
I must say, I did NOT really read much about the "greasy dust". I knew dust, but I didn't realize how much dust! Also, didn't know about the straw smelling when wet (when it stays wet).
The garage is attached to the house, 1 bay, nothing in it. Has a window which I plan to chicken wire so I can have it open (no screen) and besides the window it has a back door with windows- plenty of natural light. I was going to have an actual coop in the garage and then during the day they will go out into their run, however, I wasn't planning on them being able to get to their run freely (on their own time) I was going to let them out and in each day. Is this something I should rethink and figure out how to allow them to freely go as they please?
I will read up more on the dust, I think it's still best to have them in the garage- at least until I can invest in a "real" coop (not the 400 dollar
amazon purchased coop). Maybe next spring I'll have enough saved in my piggy bank to invest in a better, safer coop and bring them outdoors connected to their run.
I appriceate this community and all the knowledge and experience you all bring. Makes me feel a little more grounded in my decision making. It will still be a learning experience but it will be a little easier with you guys right at my fingertips!
