Our ewe, who has given birth to twins 9 wks ago has stopped grazing over the last 24hrs, she is just standing there. There is some scouring, not a massive amount, and we wormed her about 3 wks ago. Any ideas on what I can give her, I have tried hard feed and hay but she will not be tempted. I have checked for fly strike and no sign of that. Any advice would be useful.
