I have a bag of chick starter that is around a couple months old. There was just a tiny bit left in the bag, which I mixed with new feed to get rid of it. I scooped out some the other day (before I got the chicks and new bag of feed) and had it in a container in the laundry room (leads to the back door) for a little rooster that was under weight from being picked on (I now have some turkey/gamebird feed for him). In this little cup I found two tiny darkling beetle-like bugs, but extremely tiny. I do raise mealworms and superworms, but in a completely different part of the house. And these guys are just too tiny to be some of them.
Needless to say, I immediately removed the feed from the chick brooder and cleaned the feeders. I've moved the rest of that bag to the back to be fed to the adults tomorrow. I poked through the feed from the brooder before I dumped it outside and didn't see any more of these bugs, so hopefully they were just in the laundry room. Also poked through the newly bought and opened bag of chick starter and didn't see any there, either (just got my chicks and new feed yesterday).
So any ideas on what these are? They really do look just like mini darkling (mealworm) beetles. Nor does it seem like they can climb or fly (as darkling beetles cannot either). I'm sure they're harmless, but I would really like to know what they are.

Thanks in advance!
