what does "overdid it" mean

Means I have a bunch of coops to build in spring is what it means
 
	The barn's actually big enough to house 'em all (so far...) but not in their own pens. And not all pens would have outside runs, so obviously that's not acceptable!
 Instead I'm gonna have a bunch of little coops scattered here and there. I like that idea!
