super worms keep eating eachother!

[Captian]

I just got an order of super worms on wed, When I opened the bags they had a few that were eaten off of. I got them cleaned out and placed in clean oatmeal and gave them a few grapes, baby carrots and some celery. I have been cleaning out the old food and replacing daily and each day I find about 10 worms in each of my 3 bins that have been eaten off of. Is this a learned behavior? I am worried that they are going to keep doing this even though they have enough produce to get water from. I don't think they are to crowded, I have 250 med worms in a 1.5 quart tub. It is about half way full of oats and they look to have plenty of room. I also spread the produce about so it's not like they don't know it's there. Has anyone else had this problem? I don't want to contact the company I bought them from until I rule out something I did. Any help would be greatly appreciated! The numbers are dwindling

What are the temps in your tank?

Usually cannibalism is from not enough moisture, but that doesn't sound like its the problem with you.

I would say it's between 70-75 F during the day and it gets down to 65 at night.
