I've been snooping around the site for a while - getting ideas - building my coop and run here in urban Houston, TX. The grandkids helped my wife pick out six, assorted chicks in late march thinking they might not all survive but they did. Now we have one starting to crow and an overcrowding situation in a space designed for three or four. I built it mostly from scrap and recycled materials. The roof is from our old back door awning and the coop is from our old fence, all donated by hurricane Ike. Heres a picture. One puzzling question; In trying to predict rooster count, do hens sometimes chest but and fly at one another, or is that behavior strictly male?
