so i was hoping i can trust my brother to take care of my chicks (2 weeks old) to take care of them while i was gone for the weekend. Came back and their brooder was so overfilled with their mess. Anyways, 2 of them are not walking right. my barred rock is walking on his knees and not his feet. The left leg of my white leghorn is not moving at all but walking just fine on her right leg. I have no idea what to do to. I am really worried, please send some advice on what to do. Thanks all.
