Can you overstress a concrete coop?
In the case of a typical chicken coop, I do not think there is a lot of danger in overstressing the concrete (even in a sideways block) -- the main and commonest problem is the block sinking into the ground.

Can a static coop collapse?
I don't think the static weight of the smaller coops would put enough pressure on the sideways blocks to make them collapse either, but I can imagine instances where a sideways force could cause the sideways blocks to collapse. Accidentally bumping the coop with a trailer or tractor while working around it could push the coop in a direction that could cause a sideways block to collapse where the vertically oriented block would probably hold. Even strong winds could do it...I've seen 75' pecan trees with their tops bent over touching the ground (Hurricane Opal and the next morning the trees were laying on the ground among other things ). Even strong thunderstorms can generate some awesome winds. These are some extreme situations, I know, that hardly anyone will experience but they are possible.
