We thought we had 4 hens but one ended up being a roo. Our start up run is only able to hold 6 chickens at this time (64 sq ft). Is a ratio of 1 roo to 5 hens too few hens? Should I add in one more hen but that would lower the run sq ft per chicken? They are currently 8 weeks old and a bigger run will come next spring. I am just running out of time to build the run . Free ranging isn't working .
