I must be the possessor of Dumb luck?
named him Quack Quack. My Nannie, out here on the family farm, took him in when he got bigger, and he grew into a very handsome white Pekin duck. After a year or 2 a neighbor gave my Nannie Lady Duck and she and Quack Quack set up housekeeping. Late spring saw a clutch of ducky eggs and half a dozen fuzzy little babies. At around 8 or 10 days of age these beautiful babies DROWNED in an old toilet in the barnyard. Ducks, mind you. My Nannie, a seasoned farmer, cried heartily, filled that toity with dirt, planted petunias in it and proclaimed no more duck babies could ever die there. Soon after, a fox or a bobcat killed Lady Duck, there were no more babies, and Quack Quack lived to the ripe old age of 12 or so as a widower. He never seemed to want another lady companion to be honest, and was very sweet. He would follow Nannie around the yard like a puppy, feeding chickens, hoeing the garden, where he would kindly remove those pesky bugs, anything to help. Nannie also cried when Quack Quack died, called Daddy so we could all go "up the country" and bury him, and then put petunias on his grave. This is my way of saying, always be careful with any baby and water. You won't believe who can drown in very little H2O.
Try to clean her up a bit every couple of days to avoid maggots or anything. Sounds gross, but it can happen.
Just a wet rag (warm would feel nice, I'm SURE). As for milking, I'm sure others can be much more help, but if she's nursing on demand then she won't have a lot of output at first. Very small amounts throughout the day are how demand works. That's why a lot of folks milk by hand and give the babies bottles after 1 or 2 weeks, tops. I'm thinking of bottle feeding all of our young after a week or so with mom. Don't know, yet, and since we don't even have does, yet, we have plenty of time to decide.
Like the others said, the blood is normal
Now you get to sit back and enjoy the kids!
