hi everyone,
just wanted to send an update. i will post in the duck forum as well. my remaining 6 ducks seems to be doing well (2 goslings and 1 duck died). they have more energy and interest in their food. i am using the puppy puddle pads, got non medicated chick food in the store, gave them vitamins, and some apple cider vinegar.
BUT, after doing even more research last night, i think i may have discovered what happened. in the book i was using to figure out how to feed and take care of them, the encyclopedia of country living, she suggest starting grit at about 2 weeks. my 2 goslings didn't even get any grit because they died before i started giving it. they had been chowing down on all of the grass i gave them, plus i was using straw and pine shavings. i think they got blocked up.
the duck that died got a few days of grit, but maybe she had already gotten something--shavings, straw, grass-stuck.
ultimately, it was probably a combination of factors including too cold of a brooder initially, but i really think that since i was feeding this homemade diet, that they needed grit from the very beginning.
thanks for all of your help. hopefully the rest of my babies survive!
