What is the staple diet of your Manouria?
Mushrooms - daily. Mainly Oyster but sometimes other varieties when they are available. They seem to prefer Oyster Mushrooms. Mine have also learnt to eat carrot (grated or cooked), pumpkin (cooked), cucumber, banana, papaya, cantalope, pumpkin vine (a favourite of one them) and boiled eggs with shell. I have grown mullberry leaves for them, but they don't want it unlike my elongated. One of them eats boston ferns and weeds, but the others never do that!
