I found a wide pile of tiny rocks and looked at it for a while and found a hole where a few ants were crawling out. I blew mouth air into the hole and hundreds swarmed out!
This is when I remembered (and told my family) that ant colonies can be three feet wide and Fire Ants can work together to kill chickens and even calves (baby cows!) This was definitely a large ant colony. I have been bitten by Fire Ants that got into my leggings when I was little and so I tried to keep my sister away from them.
