The more eggs provide creep for an alien building, the more sturdy it becomes. There should be some limit, for example 5 eggs. For n eggs, the formula for the damage factor could be something like _1 - (MIN(n, 5)-1)0.125, making the structures 2x more resistant to damage when 5 or more eggs are around (don't forget to check that *n > 0_).
