What is the best plan for a plot of mud..?

A question about : What is the best plan for a plot of mud..?

So, at the end of the garden there is a section about 40x80ft.

It was grass last year, but it is now 10 inch deep mud. What would be the best wat to get rid/reduce the mud and get it back to grass?

The mud was caused by the chickens and the pig, which have since been moved elsewhere..

Best answers:

• The soil has likely been compacted by the pigs and there's no earthworms left alive.
  If it was a dryish area before, leave until spring then get a 1 tonne bag of sharp grit and 1 tone of top soil, hire a tiller and dig those in, then returf.
• It should be highly fertile given pigs and chicken muck.
  Hire a decent sized rotavator and work it deeply, late spring then seed or turf. This being MSE, , and me being me, I'd seed.
  I wouldn't introduce anything else.
• I would do nothing until at least the end of March. Then I would review the options, no point in rushing things now.
