Yes any organic compost including chicken manure is great for growing potatoes.
So if you can get some or have some chicken manure it makes great fertilizer for potatoes and other garden vegetables.
The chicken manure will provide nutrition and nourishment especially as the potatoes begin get their tubers.
Potatoes thrive and grow best when in organically rich and loose soil and you can even mix the chicken manure in with compost to help make a great potting soil.
