This is drastically low. I typically look for 300 or more pods of pepper from each plant. Bhut Jolokia in particular can churn them out. Don’t put chicken manure under the plant. Work it into the soil at least 6 inches away from the stem. A gallon of dried chicken manure is not harmful to a pepper plant.
Since you ask about varieties, here are a few that you might want to try.
Eva Purple Ball
Box Car Willie
Kelloggs Breakfast Potato Leaf (aka KBX)
Omar’s Lebanese is a pretty good pink.
