my girls want to do meat birds for 4H and i have no idea what size of enclosure they will need. what size brooder then what size coop and run, ect... for 25 birds! we only have a small flock of layers and i want to keep these separate so the girls get the pleasure of taking care of them so how big of a space do i need for them? thanks all also if anyone has pics of what they use that would be most helpful. not sure how long i have to get this all put together but hopefully it will quit raining long enough for me to do it.
