ok everyone i have a question i am going to build another 8ft by 10 ft coop the first coop has 17 hens in it already but some are bantams the first coop has 35 feet worth of roosts space for the chickens they have a 16 by 16 run for when we are not home but when we are home they have access to 4 acres of land how many can i exactly fit in this coop size because i have 12 more chicks that will soon need a coop and we are at least 4 more weeks away from building a new one and also i would like for the new coop to be just bantams mainly silkies so if i only have bantams in the new coop which will also be 8 by 10 how many will i be able to fit in it
