Hello again - we have twin ewe lambs raised by mum who has mastitis in one udder. Approx 3 weeks old. Both lambs have darkish dry scabs round their mouth and nose and seem to be getting better. We are topping up at night and in the morning with lamlac. One of the lambs seems to be a bit off colour and so I have been doing a bit of digging and a couple of things come to mind that I would appreciate your thoughts on so here goes ( and please don't laugh)
orf - scabs are not red though and nothing on the hooves
joint ill - one lamb isn't as active as the other (wasn't always the case) and has a thick umbilical cord which hasn't yet shrivelled away and still appears quite big ( I hesitate to use the word swollen), i wonder if she has picked up an infection? She had double the iodine when born due to the size of her belly button.
Mum and lambs are separated from the flock.
Any advice on what else we should be looking out for and first steps on possible treatment would be much appreciated.
