First let me say I'm new to posting, but frequently read the threads. Ok so I let my ducklings outside yesterday and when I went to bring them back in, they weren't running up to me. I walked out in the yard and one of the ducklings wasn't getting up. His siblings were sitting by his side. He had a blood mark on his back. I brought him in and cleaned the wound with some peroxide. It doesn't seem to be a large wound, but rather a hard peck. I'm wondering if one of my chickens got him He's eating, drinking and pooping just fine. He can't walk or balance. I put him in the tub last night to try to relieve any pressure from what I assumed possible broken leg... He couldn't even balance in the water! He's just scooting around. I looked him over several times. I don't notice any other injuries except the back.
