I let the chickens be chickens and work things out between themselves. I only recently disciplined a chicken because she kept trying to escape out the gate when I was filling the food/water. I pushed her out of the way several times and she kept at it, so I used my fingers to "peck" her a few times in hopes that she'd stay back from me for a minute. Honestly she is pretty bold in general and didn't really seem to care at all, but I can't have her hopping out when the dogs are waiting on the other side of the gate. The other thing I realized I have to look at it is my own behavior. This situation could have totally been avoided if I did the food and water before the pop door was open, and I'd left the dogs in the house.
