When some folks suggest "build instead of buy"- I don't think that they are accounting for time -- if you take time as a factor - the prices move into reasonableness pretty fast. I'm pleased with the choice I made for plastic coops when I first got into chickens- because it doesn't require the maintenance that wood needs. :O)
It takes all of a day to get a delivery from Lowe's of a wooden shed that's cute and can be retrofitted into a coop that will hold a flock of 10 for half the price of a dollhouse coop that will hold 2 chickens. It took me all of 10 days to build an 8x10 coop with minimal tools and skills.
What's the hurry? It's chickens..they don't have an expiration date and you can get them at any time throughout the year.
