I have transitioned my hens to drink from the bucket with the red nipples from the gravity fed water jug. It is a lot less work BUT I don't know if my girls are drinking enough water. At night when I close them up in the coup some times they are sitting on the ramp and the door way not wanting to go in. I have given them water in a smaller jug for inside the coup but had stopped it when they started drink from the bucket. Now from their behavior at night are some of the hens not getting enough water during the day. What should I do?
