okay, i have 6 silkie chickens on the way and i am trying to build a pen. but i am soooo confused about the size. i know you are supposed to have 8 to 10 sqft of pen space per chicken, right? isn't it less for silkies? and when you say (i.e.) 10 sqft feet is that 10 sqft total (3.1622776 x 3.1622776)? or is it really 100 sqft (10 x 10)? please let me know, cause i am sooo confused. oh and, its actually going to be 2 pens b/c i need one pen for 2 white silkie hens and a white silkie rooster; and another pen for 2 splash silkie hens and a splash silkie rooster. is that a good ratio for silkies, 2:1 (hen to rooster) ???? please answer if you know! thanks!
