I recently purchased a few Orpington hens and one of the lavenders has some funky looking tail feathers. I have done a bit of researching since and have found reference to a recessive gene that could be the culprit, but I have not been able to find any pictures to reference to. Any suggestions?I will be upping their protein as I have read this could also be a problem,but the other hens' tails look fine. Any input would be appreciated.
