Gail greased the bottom of the tins, wrapped the bacon around the edges and layered the eggs and biscuit dough to test the permutations. The whole thing went in at 350 for 12 minutes, enough to cook the bacon and the eggs.
Whatever was on the bottom cooked more than what was on the top. So, when the eggs were cooked enough, the biscuits on the top were slightly under cooked. Even with the biscuit on the bottom, the whole egg needed to be mostly firm. If you want them with a loose yolk, you would need to add the egg half way through the cooking.
The best arrangement was biscuit on the bottom, and scrambled eggs on the top. I'm a lucky engineer's husband.
