I think that once you egg them they need to be re-tamed when you respawn them . We have a thing called a Stable that you can use if you want to put them away but keep them as they are. It works something like the Vault except for Horses: http://empireminecraft.com/wiki/stables/
When ever you eggify an animal it untames them and reverts them back to their baby form. You will have to have them grow up and retame them again.
Wait for it to grow into an adult then right click on it to try and ride it. It will probably knock you off a few times, but eventually it will let you stay on. When it is tamed you will see hearts coming from the horse when it lets you stay on him. You will need to put a Saddle on it in order to control it either before or after you get off.
