Have you got slugs?
Set a trap or 3 ,slice of bread under a plate[/QUOT see some holes from birds picking but I never seem to see them at it. I'll try the bread never heard of doing it that way before. It would be a wet enough field so I'd be guessing that is what they are after.
Slugs can go down four feet into the ground to get away from cold so no need for a bus .Does some Fecker in a small bus drop them off on the middle of a big field? Surely after it’s ploughed and tilled and a few weeks with no vegetation they would have starved?
