I agree that any slow feeder is better than a bucket. Anthony, you stated that your babies pull the hay out – is this from hay nets? You may want to go with a smaller mesh; something similar to Hay Pillows.
Just like Beth, PiaffeNPassage,Leslie and TheFoxRider, I feed my entire herd with slow feeders. You will notice that they exhibit far fewer boredom-based-vices and YES, become healthier; less prone to ulcers since they took all day to eat the 4 -5 flakes vs. an hour or so.
Be sure to check out this wiki link – it has several trials/errors/successes others have experienced: http://paddockparadise.wikifoundry.com/page/Slow+Feeders
