I have a young pigeon that is not grow like his/her egg mate. The parents have quit feeding. They are about nine weeks old and the one that is smaller than it's egg mate is thin and can not walk. It still uses it's legs and wings to move around. The feathers are still inside the casing that they grow in. It has gotten some of the feathers out. He eats on his own as long as I have it right in front of him. I really want to help this little guy to live. He is as small as about a five week old. Please help!! Thank you
