We only feed ours grain as a treat, to get them coming up to the barn on occasion so we can headcount and get a look at them from time to time. Otherwise, its grass and hay.
Our original herd sire, LOVED honeysuckle! Our neighbor borrowed him for a couple of months to play with his angus girls....and thats when we found out he liked honeysuckle. His fencerow was CLEANED of it, and there must have been a couple hundred feet or so of it.
They do not usually reach the enormous sizes that most beef breeds have been bred out to be...usually a cow will average out around 1400 on the hoof, bulls maybe 1800. When it comes to processing them, we usually run around 62% of live weight for the carcass weight. We had a 7 year old cow we had to cull, and she carcassed out at 726 WITHOUT her backbone. So, she was a little bigger than average, probably around 1600-ish or so. VERY tender too...no one could tell she was that old. Glad we didnt burger the whole thing.
They CAN be rather protective of a new calf....we had one that would try to shishkebab you if you tried to get anywhere near the calf within the first week or so. But, the other ladies don't seem to mind near as much as she did. Which comes in handy when you dont want to hang around and wait for them to pee to make sure what it is. Calf weights are nice and small, 35-50 pounds? We have only had one problem with our girls since we started running them in 2003...and that was a stillborn calf. The heifer calf wasn't huge or anything, the cow didnt have a lick of trouble having her. Just something wasnt right with the calf, I guess.
Some people think bad about the Highlands since both cows and bulls sport a nice set of horns (or, as our vet calls them "clown killers"). If you are thinking Highlands and plan on dehorning them because of your concern about the horns, please reconsider getting the Highlands and select another breed that is polled. The horns are part of their built-in cooling system.....and with those heavy hair coats (one of the reasons why they are lower in fat, they dont need to build up a heavy fat layer for winter time), they need all the cooling they can get. Some Highlands will slick out real nice when the weather is warm, some still stay kinda shaggy even after losing the extra hair from the winter coat. Besides, the horns are part and parcel of the Highland package. Just wouldnt look right without them.
Highlands are not as "delicate" as other breeds of cattle....you do not need to "put them up" during the winter....ours love to be out there in the thick of it, acting like its just another day. You do need to have a shelter that they can get into when they choose to....we have a 3-sided LARGE shed/barn that they can go to get out of the weather, or for a nice shady spot. Highlands also LOVE ponds and streams....its ours's favorite place to hang out on those hot summer days. Trees are a good thing to have, at least a few, so they have someplace to scratch on. Otherwise, you will find that they will scratch themselves on whatever is available...usually fenceposts.
Some breeders do seem to overprice their stock....some do not. If you haven't found it already, check out the American Highland Cattle website, highlandcattleusa.org. You should be able to find some breeders in your area; if they are only running registered stock and dont have any steers (since you are looking for a beefer), they will likely be able to point you in the right direction.
If you were closer, you would be more than welcome to stop by and see our girls....well, you are welcome to stop by anyways if you find yourself down this way. We actually have one of our bull calfs that went out maybe towards your neck of the woods...Wernersville PA? Got pics on our webpage if you want to check them out....
