Too much calcium for either can cause problems, but so can too little phosphorus and there's something about the calcium to phosphorus ratio that's important, too.

While researching twisted tibia last summer, I read that the incidence of this condition can be lowered in broiler chickens by increasing the calcium to phosphorus ratio. Perhaps that is what you saw Kathy.
