Not the best pic because of the screen but I've never had 4 hummingbirds at the same feeder at one time. Alot of the time there is 1 and then another comes and chases the one away. What happens at your hummingbird feeders?
I have 2 newer crockpots that I feel cook too warm even on low temp for longer cooks like roasts etc . One of my new ones even has the temp probe etc. I have never been able to cook a a good roast out it.
