You should definitely be there for the hatch so they imprint on You, get some fruit and give it to them to start off with. If you don't want to use the sink you should probably buy a small pool for them to swim around in. And get a electric brooder for warmth. I would keep them inside in pain with the brooder small baby pool and food for awhile before putting them out. Hope that helps!! Btw I'm more of a chicken guy, so if I'm wrong pls tell me so I can learn new stuff too!
