A dog kennel will work for meat chickens just make sure the tarp is supported so as not to gather rain and collapse on them soaking them in the process. Covering the dog kennel with chicken wire really doesn't accomplish anything it's rather a waste of time and materials the only use it would have is containing the chicks inside until they're big enough that they won't fit through the kennel. I kept my meat birds in a hoop coop made from cattle panels with a tarp over it. It's now my pig house so I may have to build another hoop coop this year for meat birds. Cornish cross don't always range much they like their chicken feed but layer chickens and even the red ranger type meat birds will eat alot of ticks. I haven't had ducks since I was a kid but they weren't any different than chickens other than they're tendency to make a mess with the water which gets old in the winter when they do it inside the coop and they do need water to at least dunk their heads in.
