How do you clean your PVC feeders? How early can you use one?

My duck and chicks are about 5 weeks old. I need to make and install one of these, but I like to pre-troubleshoot. Other pointers or cautions?

Thanks in advance!

When the smell of the glue is gone it is safe after just a rinse.

Do you adjust the height of the feeder when they are older?

I know my old feeder used to get powdery old feed-waste in it and we used to bang it out. These look like they would need un-installed to do so. Is that true?
