Yesterday I took Hero, my handicapped pigeon out and he tried to walk on the ground. Then he pecked on the earth many times, taking some earth in his mouth and spitting out. After sometime I took him back in and today I see yellow spaghetty like poops. I read the thread on Poops here and found that it could indicate liver damage. He's having some liquid vitamin supplements also. Can that be the reason? He eats with fairly good appetite and drinks lots of water. Is there something I should do?
