So we just built our first coop. It is 5' tall, 8' long (6 nests, 3 on each side}, and 4' wide. I was planning on building a pen around it like so I was thinking it would be near 10' long by 8' wide. Does this this sound like enough room for 7 chickens? They will be able to free range durring the day for a few hours here and there. But mostly worried about winter when they are more isolated to there coop and pen. And we don't have extremely harsh winters, but have gotten snow maybe 2x a year.
