This isn't related to german shepherds, so I am sorry if I am doing wrong by posting this, but every one here seems very creative, so I thought I would ask.
We recently moved to a farm and have chucks. lots of them, and as we also board horses, this is not a good combo. One field is unusable due to the burrows. Any good Ideas on how to get rid of them? I used to have a really handy JRT that would have done the job, but he has passed on. It is illegal in my state to trap them and "relocate" them, (Not that I would do that to the neighbors anyway.)

.222 + scope. Hollow-point rounds.

I've got a JRT I could lend you, permanently.

Don't know what my wife would say about giving her dog away though. . . .

Get a 22-250 heavy barrel with a 7 power scope - problems solved.

We use to put one capful of "Household Cleaning Amonnia" in the burrows and they would move out fast, but as for the field you will probably will have to plow and resow. GOOD LUCK!

The problem with blowing their little cussed heads off, is that we just moved in and there is way too much to do already, to spend the day out there waiting for said heads to present themselvs for removal. (and yes I know, "center of mass", just using an expression <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" /> )
My wonderful husband was out there today and I think that "the poor guy" will just have to take the day and sit there waiting for the opportunity. Such a shame and hardship for him to have to miss out on unpacking the boxes and moving the furniture. <img src="/ubbthreads/images/graemlins/wink.gif" alt="" /> Not to mention wrangling the 4 kids.
We use the field for grazing, What would the effects of the ammonia be? How extensive would the kill on the grass be?
Also, other than gravel, any suggestions on repairing the holes?

It's uncommon for a terrier to have the ability to killl a hog underground. When they do, they often take one hell of a beating. That's why I quit hunting Border terriers and switched to JRTs. My male border terrier could kill a hog or coon below ground, but I wasn't in to the punnishment he was willing to take. The correct JRT is a baying dog and will either bay till you dig to it (locator collar on the dog), or flush the quarry if it has another way out(often). The the exit holes are either netted, or your sure enough of your shooting that you don't blow up a dog that may be right on it's tail. Farmers will sometimes pour water in the holes to wet the sides, then pour gasoline down and light it. Not very sporting but I'm not a farmer loosing crops or having livestock break legs in the holes. The summer holes are often in the middle of a field, and being shallow, will colapse under the weight of farm equiptment, breaking axels in the process. If you use the gasoline, be sure you aren't standing over one of the escape holes when it's lit. You kin loose yer shorts that way when it flashes.
A .222 is great in open country out to about 150 yrds. After that, a 22.250 is the ticket. trapping works with apples as bait. Don't use the body traps if you have small dogs around. They will kill a dog. The Havaheart livetraps work great.
All this being said, many hogs are just about into hibernation by now. Winter earth work with dogs is almost always coon or possum.

Mr Scott - Judging by your knowledge and coolness on this subject your name must strike utter fear into the hearts of the hog/coon fraternity <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />

Tip from a professional trapper...

No kidding Willy, since you asked for creative solutions.

We bought a house a few years ago that had not been lived in for over ten years. We have almost 10 acres - and about 4 of that is deep woods - a haven for coons, woodchucks, etc.

Among our initial findings were a woodchuck familiy living under our porch, and a coon family just above our fireplace at the bottom of the chimney. The coon family HAD to go immediately. A .22 was not the weapon of choice for that problem, so we had to hire a trapper.

He gave us interesting advice. At the time we discovered these "families" we were not yet moved in, so our 4 dogs were not here yet to get busy marking territory. He told us that critters such as coons and woodchucks would respond to territory marking by humans. Especially human males. Since beer is only rented anyway, we encourage territory marking by humans as well as dogs during all parties.

I'm not sure how large your "field" is that you're having problems with. Maybe this trapper was smoking crack, but we implemented his suggestion and have not had any problems with coons or woodchucks hovering too closely ever since.

How's that for "creative?"
