put the seeds in 4 weeks ago there are up 5 ins went there this morning loads have been dug up how can i stop this

Do you think it's an animal which has done the digging?  Squirrel? Cat?

Putting netting over the manure might help but it does depend a little on what is doing the digging.

What have you planted?
Is it the green mamure that is the attraction or is there something from a previous crop?
It may be that the bed has plenty of worms or some pest such as leatherjackets or slugs.

its winter grazing rye all so think its a fox or  squirrels or pidgins 

[Yorkie]

I doubt it's pigeons.  Squirrels play havoc with my lawn at this time of year when they try to plant conkers from the horse chestnut trees 

Could be foxes if they have access to your back garden - did you put chicken manure pellets down when you sowed, or anything like that?

no
