Update: Coop is complete! Water system is functional.

After a mishap in choosing the wrong size hole saw, I purchased a new 5 gallon bucket to start all over. I used 1 1/4" PVC along with water nipples. Bada-bing! Chickens now have clean water inside and outside of the coop. Girls are almost 7 weeks old. I included a few pictures of them as well.

Looks good, but noticed that the nipples look a little low for the chickens to get at them?

That would be a negative, Ghost Rider. They went to town as soon as the water flowed. On the inside of the coop, I tilted the nipples just a bit.
