I understand flight CAPABILITY, but have a question as it pertains to flight BEHAVIOR. I am working on a chicken coop to be completed by spring and window shopping "pretty" and personable chicken breeds. I live in town on an 0.8 acre fenced lot. The proposed chicken coop is sufficient to serve as the only space (42.25sqft hen house, 120.25sqft roofed run)....but sufficient is never my goal. I can add more run space or build an accompanying tractor, but would like to allow the chickens some semi-supervised free-range time if possible. My research indicates that D'uccles are VERY flight capable. Clipping wings is great, but guaranteed to result in a Murphy's Law moment when I miss a scheduled trimming. Even with clipped wings, they can very likely go over my fence (where they would be prey to my neighbor's less than chicken-friendly dogs). So to my question.... IF I hatch and handle the chicks from "birth", socialize them with my dogs, and do not let them about the yard until mature....is it possible that they will not form flight "habits"? Or is it the reality that unclipped D'uccles will announce their presence by perching on my neighbor's rooftop unless I make the decision to contain them at all times? P.S.- I am still deliberating my options but would appreciate any recommendations of breeders with especially gorgeous birds, particularly in Mille Fleur.
