Lamb not making weight

[rhysjj]

Might be a stupid question but sold all last years lambs as usual as stores but kept one for myself, lamb went backwards a bit despite being on good ground so bought it in wormed and sent back out. Weighed before I put out and he was a march lamb and is only 25kg. Any advice? Is it normal to be this weight 6 months down the line? He's a welsh badger by the way. Rookie question I know but thanks in advance

Cobalt / copper lock up? Known as 'pine' or starvation to you and me. It's a mineral lock up so what they eat can't be converted into growth.
A wet season doesn't help either - grass has been water on a stick, so DM intake low.

What wormer did you use? Could be resistance

Does he look wormy/ill-thriven, or healthy but just small?

Silly question, as it isn't clear from your post, is he kept alone? Stress of isolation wont help
