I did everything you did, but in the opposite direction. I got the chicks first from a NH chicken swap (great fun!!!). Then I discovered BYC from the card the seller gave me. I ordered the coop and immediately grew out of it! We finally have a nice run and coop ready for the winter, but it was close!
5 of my girls are now laying, I guess I will have to wait for spring for the rest. But I love the birds!!!
