Oh, mine are pretty spoiled
But mine are Red Sexlinks and a Buff Orpington, and they could be less stubborn. I also handled mine a lot when they were growing up, and maybe they were used to me telling them what to do.
I can see how a water bottle would work....I've used that with dogs, too. My coop is under a big mulberry tree, so I always have sticks readily available, and don't have to remember to bring anything with me. At my age that's a plus.
It does sound like what you are doing is working with yours, and that is the ultimate test, isn't it?
