After having used the poultry nipples from QC since day 3 of chicks, (they are pushing 6 weeks old now) I am always pleasantly amazed at how clean the water and the inside of the chick's house is kept. After I close them in at night, making sure they have plenty of food and water (1/2 gallon), I go to bed knowing that if they get hungry and thirsty before it warms up enough in the morning, they have food and water.
One caveat though...I made them an outside water for daytime out of a #10 can (gallon sized?) with one end cut open, and a couple of holes 1"up and then fill it up and put an old pie pan over it then flop the whole thing over, a little water trickles out and fills the base. Boy do they love taking big swigs from that!
I imagine it being similar to us taking a teaspoon full of water at a time to taking a mouthful. While a teaspoon will work, we certainly wouldn't prefer it!
So, my thoughts are, while they might do fine taking one drop at a time, sometimes having a full beak-full can be wonderful! I'm going to provide the water for inside the coop with the nipples and a bucket, but have a bigger source for them to get a mouthful outside.
p.s. when I bought them from QC, I bought 3 times what I needed figuring to spread the cost of shipping and to have spares when something breaks. That made them very, very reasonable, certainly still less expensive than a big watering can.
