Hello! I have 14 chicks (currently 3 weeks old) that we are working on a coop and yard for. We are hoping we will be successful in allowing them to be free range at some point and want to start with an uncovered enclosed yard (we will cover it ASAP if we have predator issues). The coop has been ordered and will arrive this week and we can begin to prep that (paint walls and tile floor). I don't have the dimensions readily available right now but it's fairly big with a man-door on one side and the chicken door on the other end. There are 4 nesting boxes on the right and roosting perches that run the length on the other side. I believe there is also space for storage buckets to one side. The area we want to use for their yard/run is where our daughter's swing set/fort used to be. It's about 12-15 feet across and it's an octagon shape. The ground is covered with pea gravel and has PLENTY of weeds and grass peeking out. Is pea gravel suitable or should I change it to sand? Second question; I am sure that they will make short business of the grass and weeds. Can they be fed fresh grass clippings when we mow? I plan on giving them lots of fruits and veggies (as per the books I have read) too. We have raised Pekin for our pond for three seasons and when I started this I thought chicken were going to be very similar....yeah, not so much....there's a TON more to consider! Thanks so much for any feedback and as I said, this is just the first of MANY questions!
