Ellen! You are a DUCK person! YAY!
The ones you had (was it last year?) that was a temporary situation, right?
Well, it sounds like the imprinted on humans, which is natural if they were hatched in a classroom with many pairs of eyes watching their every move.
For bedding, I use old towels in the tote or tub and toss them in the washer each day. When they are 3 or so weeks old, I use shavings. You just changes as needed and trust me, you will know! LOL
I use the bathtub as a brooder. It is easier to keep clean and when I take out the towels to change them, I hose everything off, ducklings included. It is warmer in the house usually, so added heat is on an as needed basis. Look for the same signs as in chicks. Huddling=too cold. Panting or spaced way off=too hot. If they are in the house, it is more fun, since it is easier to interact with them.
They should be on non medicated waterfowl or game bird starter for the first 2 or 3 weeks then they can have grower and a little less protein, but you kow that already. Treats are ok, as long as they have grit to go with it. Lettuces, watermelon, like that. I don't bother with treats til they are on the ground, that way I don't have to bother with the grit.
They will love to have a lukewarm bath for a few minutes a day as long as they get towelled off and back under a heat lamp right away. Have your camera handy, it is fun to watch. I use the kitchen sink for ducky baths. It is deep enough that they can't jump out and splat on the floor and high enough that YOU don't have to be all stooped over watching the cuteness.
Sexing is impossible without looking at the vent at this stage. Peeping alot... I would have to go the other way. My hubby talks WAY more than I do
You know you can email me anytime, Ellen and call if you want.
Have fun and don't sweat the stinky stuff. They will be grown and outside before you know it. Enjoy those babies and I know you will spoil them like I spoil mine!
