I have 6 ducklings right now. They are MUCH MUCH messier than the 15 chickens. They are very entertaining to watch and cute as can be, but I dare say they are more work in the brooding stage.
They poop a lot. In volume and frequency. It is very wet smelly poo. They can't go on shavings for a couple of weeks. Bounty couldn't keep up with this poo, so I am using recycled rags under them. I probably go through 12 a day. Once they are done with them they go in the trash. I thought I was going to rinse and wash them, but they are wayyyy grosser than cloth baby diapers!! Thank goodness I can get the rags free from my dad.
That being said, I will probably do it again. I would never get more than 6 though... thats enough! LOL
