So this means that the pups get let out during the dark hours when the chickens are roosting for the night and they're pinned up during the day, unless I'm down in the pasture. So a routine has formed:
After sundown, I head down to the pasture. Harley & Squirt usually follow me down the holler. I appreciate them because they flush out and skunks or other critters along the paths.
In the pasture, Alfredo and Feta are excited to see me.
This is the best time to feed them. My chickens REALLY like the dog food, and will actually get into the pen to get at the dog food. Feeding at night stops any problems. It also lets the pups digest throughout the night, and they'll relieve themselves so they don't mess in thier pens.
These goofballs will spend the night snooping around, barking at any real or imagined threat, and thier presence keeps the predators at bay.
