I have a rooster in a cage right now, was infested with mites. He's eating great now, he's very, very thin. I'm giving him regular pellets. chick starter, scratch, sunflower seeds. Anything I can think of to put some weight on him. I've been giving him extras, broccoli, pumpkin puree, a few raisins, apple. He hasn't touched the grit. his poop was dry and regular when he first come in the house, but now he has diarrhea. Which I figure is normal from all the extra foods. Another thing I noticed his crop never gets big. Is this normal because he was so thin? Is this normal to never eat grit? Even when he doesn't have access to pebbles?
