I've been dealing with ants too! It's those tiny ones that bite!! They were all along one end of the run. Poured lots of boiling water on them over a couple days.I'm glad that you at least got something. Yes, it was a bit cooler here this morning after last night's rain. I took care of 5 anthills that were being built in my backyard, and one of them was being built too close to my coop and run for my comfort. At least I have time to do that now since I'm no longer animal sitting for next-door.
Your pullet is practicing on how to be a big girl.
BTW, today is the last day to buy incandescent lightbulbs for any who prefer those. After today, stores are not legally permitted to sell them.
