A great deal depends upon your relationship with the hunt. When I was keepering, the local hunt and myself got on really well, even to the extent of comparing shoot/meet days before the season so that there was no clash. That relationship worked really well and we never had a problem.
Many years ago I was doing some work on the shoot and the hounds came through the large wood I was in, it was very interesting to see how the birds reacted, in the main, they either just ran off or flew a very short distance. Within an hour all was back to normal, something, to be honest, I wouldn't have expected.
It's very sad to hear that in some areas the hunt and shoots don't get on, we are all in the countryside and especially in these difficult times surely it pays for anyone involved in country sports to get on, there are enough antis giving us grief without the locals falling out!
I'd echo this i used to shoot a lot with a gun pack and it would often be invited to shoots at end of summer aug/sept time and hunt the main woods out.
And it really is surprising to see how few birds are flushed/moved when the hounds come throu and u know there is a decent number of birds in there.
It could well make a difference the number of hounds, this gun pack only generally ran 3-5 couple at a time and they were steady to birds/stock/deer and didn't even give them a second look, possibly with a larger pack and if lss steady it could be more of an issue.
I once had a lost hound from the mounted pack come down the feed ride just after i had whistled the birds in, was a slight panick from the birds but after i got the hound in the back of landy and went up the feed ride the birds were feeding just as normal ( again early season)
Also these shoots weren't massive in numbers, and early on before season started so birds less jumpy/wise, but they still came up throu the season too and hunted on sundays and shoots generally welcomed them as they done a good job.
I know at this time of year birds are getting scarce anyway and quite wild and jumpy so it will be hard to tell exactly wot damage has been done, but i doubt it will be as bad as u fear and definately far less than u driving the birds out the wood and then chasing them about where they land as u pick up.
But the hunt should still not have been anywhere near he land either, i know it won't be easy to keep a pack of hounds inline thou.
With the english hunting law being the way its been for so long now, will most hounds not now be only used to hunting the scent lines rather than live foxes or even when trained on fake scent will they always draw on a live fox scent?
I've only really been invloved with hunts/hounds in scotland where still normal/legal to hunt the fox as long as its shot, works quite well as a tool with dealing with difficult foxes/places
