I have a 5 month old Barred Rock Roo who has always walked a little funny. His legs are bowed-in and he seems unstable. He also seems to have lost some size in the last few weeks although we have had a real stretch of cold snowy weather so that may be the reason. His feathers look good. His wattles and crown also look healthy and deep red. Appetite is good. He hides out under the coop more than the others but I think that is because he cant really stand-up for himself as his legs just dont seem right and the other Roo is starting to get all full of himself(also 5 months). Any idea what the leg thing is or could it be just growing pains?
