If you have shelters for your does or fawns to go into to eat my choice hands down are the stainless steel hog feeders. They hang on the wall,fill easily,are easily cleaned and will last forever and are usally inexpensive to purchase.
We use Outback feeders. We like the design - not a lot of bracing for bucks to catch their antlers on. Also with the runners on the legs, you can easily move them to a fresh place in the pen. Plus they have an extended tube in the center for fawns to reach. We think they are the cadillac of deer feeders.
If you need an inexpensive gravity feeder here is another option. Pretty easy to get,easy to fill and won't clog up and can be easily placed in shelters and will last forever.
Best of all if your on a budget they won't break the bank until you can afford to update. We use these on our fawns and for our adult does and they work awesome. We even have some that are double sided to allow more mouths at the table!
