Thanks for the links Toni, enjoyed reading them, they also led to one of our favorite sites, BackYardChickens.com, we are learning so much reading through the forums!
Porkpal, ours will also be one designed by hubby based on materials we manage to collect and yes, predator-proofing will be high on the list, we have racoons and fox plus hawks here. Hubby saw one coop where they had added hardware cloth to the base of the entire run to prevent any burrowing critters, something we did to prevent gophers entering the raised beds and the new lawn.
