I bought some seeds at the health food store. It is meant for making alfalfa sprouts.
I had an "indoor herb garden" that didn't sprout a thing. It isn't anything special, just a metal bucket with soil in it. I sprinkled about 1/2 teaspoon of the alfalfa seeds on it to see what would happen. I just left it on the South facing windowsill and watered it when I remembered.
My house is really cold because we have thin insulation and don't run the heat at night. I'm surprised anything grew!
I'm sorry to hear about your lop ear. I don't think this bunny is going to make it... I let him go and he can't hop properly, he falls on his side a lot. Something is wrong with his spine or back leg.
