My ladies seem to have endless guts when it comes to eating. With the recent cold snap here I have had to give them fresh water twice a day outside in the run, in doing so I have noticed that they have increased their appetite almost double. I started giving them an 18% protein mix along with several helpings of cracked corn along with bread and yogurt mix. Two of them have started lying again and they are all healthy with no sign of worms or other parasites. They are all between 12 and 16 months old. But every time i go out to them they act like they haven't eaten all week, Whats up??
