Go here for information on nipple waterers- http://www.picturetrail.com/sfx/album/view/23146070 Please excuse the technology I have used to present this. The IT nerds at work have been very busy and have not been able to help me much with this. I did this over the weekend with the technology I understand. You can see how digitally challlenged I am. Hopefully the geeks will be embarased by my efforts and redo it correctly. Yeah. Just as soon as they get tired of playing video games on the clock. Since I know who manufactures these products I will be able to supply them to backyard chicken people at aobut the same prices but the shipping will be far more considerate.
