Also, my friend told me to put a ping pong ball in the water to prevent the water from freezing . I tried to have the ball in there and I thought maybe that was detouring them from drinking so, I took it out . Made no difference . They still don’t drink from the bowl
They can reach the bowl, I fill the bowl each day in front of them. Yet, when I let them out in the morning into their run, they go directly to the other water feeder. I notice the water level in the black bowl and have noticed it never goes down .
Thank you for your advice.
