To cook this congee, you don’t need strong hand muscle to keep on stirring it on the stove top as what you would for the usual plain congee. The reason is that some grains such as brown rice and black glutinous rice can’t break down easily and hence have fewer tendencies to stick to the bottom of the pot. Furthermore, the chicken carcasses and pumpkin play a role to minimise the rice from sticking too. However, I strongly recommend that you use a large stock pot that has enough depth so you need not worry about spilling over. Alternatively, simmer the congee with the lid partially opened. This congee will take you two hours to cook from start to finish.
