Moorhen

Hi I have just joined this community. I need some advice please. A moorhen has been pecking around my garden for the past couple of weeks. I have a small pond in the front garden but it is not interested in that. It's in the back garden where the bird feeders are. There is a pond in a park about half a mile away so I think it must have got lost somehow. My question is,do I leave it to make its own way back or do I try and catch it and take it back to the water. It's destroying my grass. Thanks.
