So I brought home a 7 month old silkie rooster a few weeks ago. The first week he was great, well then a few days ago I noticed he stopped crowing at all, and didn't want to come out of the sleeping area unlike every other morning where he couldn't wait to cone out. Now he just sits in one spot all day, can barely hold his head up and is no longer eating or drinking on his own. Yesterday I started giving him Vitamin B12 complex and he also drank a tiny bit of water through a dropper, but still has no interest in eating even when I tried just giving him mash or canned kitty food he wanted nothing to do with it. It's breaking my heart, this was my first silkie ever and I was so excited to have him, I cannot stand to see him so lethargic, I don't know what it could be...his poo looked completely normal, and he is not sneezing nor does he have any discharge from his beak or eyes. He was totally normal up until that morning. Any suggestions please let me know asap...thanks! Here is a pic of how he looks now.
