I have 11 guineas that are around 2.5 months old and one has developmental issues. We call him Weeble. He is smaller and much more round that the rest of the flock. He also weebles - woobles - waddles when he walks. He can fly just fine, and is always in the roosts at night, but we notice he falls down and just covers himself with his wings sometimes. My flock has only been free ranging for a few days (locked in their coop at night) and he seems to keep up most of the time. Just wondering if anyone know what may be wrong with him or if there's anything I can do to help him. I circled him in the pic (i know its not the best, but I can never get a good shot of him).
