I don't see the point.
The pellets; or should I say the chicken droppings; are pelleted and covered in a lacquer to form a slow release fertiliser, otherwise it would be quick release if applied it its raw state.
Over the season the subsequent water content and temperature of the soil acts on the lacquer and releases the fertiliser in an amount that the plants can handle.
What you are doing is speeding this process up so the plant will run out of fuel sooner, plus the fact with courgettes and squashes you may find you get more leaf production at the expense of fruit.
I never feed my curcubits until fruit has formed so as to avoid this situation.
