My hen is about 1 and half years old. She is a silkie. Yesterday she started acting very disorientated and seems to be dizzy. It takes her 2-3 tries to walk through the "chicken door", she walks right into the wall a few times before she makes it in. She is free ranged with 2 nigi goats, 1 silkie rooster and about 25 more hens and babies. There is a possibility she was injured but I need to know if there is any illness that could be causing this and if so will it spread to my others. Also there seems to be a lot of "orangie" colored loose stool this past week. The chickens have not had any change in their diet. What could it be? Any advice is greatly appreciated. Thank you! I will not be able to check back for about 2 hours so don't give up on me please. Thanks again!
