Got a lamb, now about 6 weeks old who isn't thriving. She's one of triplets and her 2 brothers are doing fine. She was the runt when they were born, so she was supplemented for the first 3 weeks and was doing well, but she seems to have just stopped growing and looks poor and grubby but not ill as such.
She does a lot of stretching, with her back legs behind her.
Do you think she might have bellyache or are there other things that cause this odd symtom?
No sign of bloat or scouring. They've been on grass for about 3 weeks now.
