I suspect these are breeds that you have owned or own. Writing about a favorite one from your flock for each breed would make the article more interesting.
I have used this waterer before and it was not good for sure! I like the idea of using it as a feeder.
I use a similar system but use a heat plate and washable foam shelf liner that can go into a washing machine.
The article would be much better if the images were fixed and there were more build details like a materials list and a schematic.
I see that the author fixed a lot of errors in the article so it is better. I have found that corid it the medicine to use.
