D'Uccles are very timid, sweet chickens. They are at the bottom of the pecking order around here.
They can be easily tamed, and are attractive to hawks. So I give them plenty of cover to hide under. Mine are mixed in with my large fowl, which I really don't recommend if you have aggressive large fowl. They are easily kept from eating by aggressive chickens.
Mine do get food, but they really have to wait for a chance to run over and eat quickly before they are "discovered."
If you mean to coop them up at night in a rabbit hutch, that is fine if they are protected from ALL wind and cold. They aren't terribly cold hardy since they are so tiny. Not like the fluffy large fowl. I give mine a 100 watt bulb to huddle under if they need it in the winter. I have taken Chick-N-hutches and put plywood over the vertical faces of them to cover the drafts and they work ok. I have sinced moved them into my shed coop for ease of care.
I assume you mean to give them a run to be in during the day. They are fliers...they fly like helicopters over any fence they want. However, they DON'T like to go away from home. They are security-oriented and don't go outside my fencing. They are afraid to free range far away from the coop.
If I just had d'Uccles I could just open the gates of my pens and they wouldn't even go out most likely, except 20 feet away once in awhile, lol. I used to free range my fowl and the d'Uccles didn't want to free range at all.
