Chicken muck

I have been given access to a good supply of well rotten pure chicken muck  (compost)
    how much should i use on the allotment, I have read 45 lbs per 100 sq feet but this does sound very thin to me , can anyone help please  .

I am moving towards a no dig system
Cheers
Ron

I get a load of fresh chicken muck each fall and spread a barrow load for every 9 sq ft. Yours would be 1/3 that. And yes, be prepared for tall plants and heavy cropping.
