Just got my little flock of 6 pullets yesterday, can't tell if they are using their auto waterer; it is the kind that fastens on the wall with 2 holes side by side each about 2 inches wide, so I put out a bowl of water and they went straight for it. How do I know if they are using the auto one, should I raise it up? Now the holes are about 6-8 inches off the ground. Love this site! It has been very helpful.
