I am new to raising chickens. A couple of weeks ago I purchased a premade coop. Two days ago purchased our first chicks. After reading this post I'm concerned for their safety. What if I purchased 12"x12" concrete blocks and surrounded the coop? It's not large and can only accommodate about 6 chickens.
I did that for the ready-made coop/run I bought to house the chicks my broody was hatching. The 12" square concrete pavers were on sale at Lowes, so I surrounded the whole thing. The run also has a wood roof and has 1/4" hardware cloth on the sides. I close the chicks up at night and added deterrent additions to access points as well. The only threat I see is if several large coons stand up and all push on one side, the whole unit may tip over. They could probably plot that.
