How big should my coop be for 3 silkies and 2 ameraucanas. So far I have designed a coop that is 3x4 with one or two nesting boxes(leaning on probably just1) and a run underneath that is also 3x4 they will be free range as ofte as possible(im a stay at home mommy) do you guys think this will work. These will be my first chickens on my own. I live in central florida. Thanks in advanced
