Baking bread and roasting chicken in the same oven

If I roast chicken is in a foil pan covered with aluminum foil sheets and I bake bread on a open pan at the same time in the oven, is the bread still considered parve?
if it is OK, does it matter which is on the top shelf?

If it is not OK in the same oven , what about an oven that has two ovens
a) large regular oven
b) lower oven beneath it

Will that work?

Our ovens have ventilation. There is generally no moisture in the ovens so it would be ok to cook the chicken and bread, and still consider the bread Pareve.
