My chicken math:
Thought city ordinance allowed 3
Told hubby I'd be getting 6
Ordered 8 in case some died
Picked up the 8 and realized they looked lonely and small in that big ol' brooder 
Went to the local feed store same day and got 4 more
Waited a week and went to browse the feed store again, it was my birthday so of course bring home 3 more
Hubby officially thinks I'm off my rocker to have 15 chickens in the house
Found out yesterday I can actually have 19-20 chickens on my size of property!!! 
SERIOUSLY considering going back for 4-5 more this week before the age difference gets too big
I now have 15 pullets but will end up with 20 before next year 
They are: 4 Rhode Island Red, 4 Buff Orpington, 3 Black Australorp, 2 Ameraucanas, 2 Welsummer
