This is a great starter backyard chicken coop for just 1-3 regular sized chickens.  I am an owner of a lone stray chicken, and I bought this for her.  It works great for what we need it to do (give the chicken a safe place to sleep).  We have the coop inside a dog fence that has is a much larger area and has been secured down at the bottom.  If it was not, I would be worried about animals getting underneath this chicken coop and getting to my chicken. So anchor it down if you live near dogs or other burrowing/digging predators of chickens.  So far we love our chicken coop, and I hope our chicken does too.

Pros: Great value (much more expensive on other sites). Sturdy quality parts. Fairly easy to move around with handle and wheels.
Cons: Instructions suck. Pieces are not numbered. Hardware is not labeled. Packing foam gets in grooves of parts - so clean out first!
