Good question.
Coop: A pen or enclosure for birds; jail; To keep in a coop
Cote: A small shelter or shed for fowl, sheep, doves, etc.; a cottage
The stressed difference, for us, is a matter stewardship. I could call the structures we make for our chickens "coops" and ,most likely, nobody would say a thing (Resolution would).
The difference between a coop and a cote is a principle of the quality of care which leads to healthy animals. Domestication is not the option of the creature. So, there is a responsibility in the hands of those whom have a life in their control.
Chickens in particular have needs that are very often neglected. I nor you fly but, they do. They have systems and processes in their bodies that rely on the exercise that flying provides. They also would not, in their natural habitat, eat their own feces.
A cote offers an ability to meet these needs.
With that said, a cote is something you could walk into. Perhaps a shed; something with a peaked roof. It offers room for the birds to fly. There is room for the food to be off the ground and away from their excrement.

Notice the food off the ground and the "training" roosting poles
