My Blue ameraucanas roo who I recently moved to the batchelor coop (there has been no fighting, but before that he was in a big cage getting introdused to alabaster my other roo.) so the situation was obviously stess full. I just today noticed when taking him out to free range that some of the tips of his feathers are getting a brassy color. he is fed the same feed as everyone else and all my others are healthy. i have never seen this before but remember a thread where a rescued roo had it when he was malnutricious. I have done a search but cant find anything. I intend to give him some vitamins and extra yogurt and eggs later but does anyone know what this is, what is causing it and should I be alarmed? he is a bit on the skinny side, I have been trying to cahnge that he was not as high on the pecking order before I selected him as the keeper. Now I am wondering if i made the right choice... I will try to get a pic in a few
