You're quite welcome! Just make sure you use a 3/8" drill bit and screw them in "straight-on" to the surface of the bucket...that way they get a great seal. Best of luck!Thank you. I looked at your "switching your girls over to HWN" but I wasn't sure what size the bucket was and how many hens you were supplying. I plan to use 2-3 gal buckets....way lighter than 5 gal buckets. But I will copy your pic and place 4-5 nipples per bucket. Thank you!
