Redesign my run... Need Help!

[Roberts2100]

OK here is my idea. Where the post is for the outside run I want to fence off of it to the back to give them a 30x40ish. Would that be enough for all my 19 chickens now? I would like to add another 18 or so chickens to a total of 38. The total run now is 30x85. Also, it looks like they have scratched all the grass away thought the winter. Is this a sign they need more room for what I have?




Thanks for any ideas!!!
James
