My ducklings, who are still in an indoor cage, have been drinking out of a bowl. The problem with this is that they like to swim in the bowl and poop in it, splashing the waterer everywhere, constantly needing me to change the water and clean the cage a few times a day. Recently, I've bought a waterer that they use for guinea pigs and put it in the cage. I removed all other waterer, and hung the waterer just above head level, and hopefully out of interest mess with it and figure it out. Are they capable of drinking out of this type of waterer?
