lamb cant really stand/walk on it's back legS (3 months old): any idea what could be causing this?

[bubbleblower]

It can walk fine on it's front legs but it's back legs aren't holding it up well, it can walk on them wobbly (like at start of video) for about 5 minutes but after that it lies down. Yesterday all my lambs were fine but today I noticed this lamb with this problem. It doesn't have any maggots on it,the lamb was treated for maggots, the lamb is 3 months old . She doesn't have swayback https://photos.app.goo.gl/kbnmevmXZM9BLv3c6 Https://photos.app.goo.gl/ZDWZ6V3UwCEnDqJX8

How do you know it's not swayback? As the lamb grows the pressure on the spine increases

Spinal abscess?

Have seen that in Texel cross lambs that are doing very well/growing very quickly.

In them it has been caused by an abscess on the spinal column. A course of antibiotics (pen/strep in our case) has sorted it.

We had one that sounds very similar - vet diagnosed a spinal abscess so gave it penstrep daily. It improved over a couple of weeks but went downhill after that so was put down this morning. Ate and drank fine - just couldn’t walk

As above, antibiotics and try an anti-inflammatory as well.

Sway back looks the same but onset more gradual as weight increases. It is a spinal problem as front legs ok. Outcome will probably be the same I'm afraid.
ps why the beer kegs in the field?

Could be white muscle disease. Try a jag of vit E
