The only wormer that really works on goats is an Ivermectin one............I use Oramec at twice the sheep dose...............straight down the throat.
Eprinex is useful to make sure that lice, mange etc are not being harboured but it really does not work on goats for gut worms.
The worm that does the most harm in a goat is Haemonchus Contortus...Barber Pole worm and  Ivermectin is the the only one that is known to be effective.
Check that the wormer you want to use is effective against H.Contortus...not all are.
The fact that your goat was uncertain on her feet suggest to me that she is anaemic from worm damage and that worm will almost certainly be H.Contortus.
This worm is on the ground, you cant stop it.  You can only attempt to break the lifecycle and then keep on top of it.

My vet told me that as my goats are yarded, there is no need to worm them.

Once they have been cleared of worms and are not re-introduced to infected pasture you should of course be ok for yarded goats.

That is right of course..............but this does mean no fresh cut grass can be fed, only branches.
If you feed any cut grass,   worms could be hiding deep in it particularly at this time of year when warmth means the larvae are higher up stems.

I use ivermectin and do a poo sample myself.

I usually do a poo sample myself...every morning 8.30 sharp

Carl, too much information. 

The only fresh grass my goats have is from my garden so that should be clean.
