Poorly lamb...help!

[GreenerGrass]

We used Volac. I used it last year successfully on 3 lambs & have tubed 2 with it 2 weeks ago, they are doing just fine. They are pooing just fine

Sounds like it may be another thing. Sorry but the symptoms seemed so similar, mine would suckle the colostrum (also Volac Volostrum fwiw) for 1 or 2 feeds, and then after that just refused to suckle. I lost two from it before I realised. They just refused to eat. You could certainly hear them letting a distress bleat out when dunging, sometimes some dung would come out but a soapy enema on 3 further ones literally transformed them, got them feeding and after that they were on lamlac with no issues.

The common trend on here with lambs that are not feeding is to skip a feed, and not fight them they will come round. But since yours have already missed a few feeds it seems there is something else. I hope you have luck with them, it is not normal for lambs not to suckle, especially if they did originally. If you are going to lose them anyway I would try an enema it really did sort mine out, and you will know soon enough when dung comes out if it was an issue.
