have they had access to anything the might have maggots or worms? Ducks aren't equipped to handle those things, and i had some die , sounds like the same way. The maggots eat the inside and then they foam.
Hope this isn't the case with yours, try calling around for some vet ideas.

Sounds like they may have some type of respiratory illness and need waterfowl-safe antibiotics.

Hey, they haven't been around any maggots while they were here with me.
I'm not sure what they might have come in contact with when they were at Tradeday with their other owner...
That is waht I'm thinking they might have..a respiratory infection. I gave them some tetracycline medicine mixed with their baby grain and they ate it. They aren't spitting that up that I have seen today.. But, just because I haven't seen it doesn't mean they aren't doing it again. I am just hoping they will get better. They are sweet babies

I hope they get better too,
I mentioned the maggot question because while I let my ducks and chicks out one day, they found a dead snake and feasted on the new tenants. I figured they were no different from any other type of bug they ate, but I was wrong. But again mine were adults, not babies.

It's Easter morning and we just gave 3 baby ducks to our kids for Easter. All 3 are spitting up mucus also. I am SO worried. We've had ducks as pets before and never had a problem. It will break the kids heart if they die. Where do you get Tetracycline for baby ducke and how much do you give. VERY WORRIED! It's one thing to break my heart, but a whole other thing to break the kids heart. Please help. thanks, Pam

Just noticed this evening that one of my baby ducks was puking and also both of themlook like they have sores on thier necks and on the tips of their wings.

I had been putting them in the tub with water to swim around and was also wondering if tap water for this is one safe or two the reason for the sores on their wings and neck.

Any ideas and remedies for this are greatly appreciated.

Thank for your help.

i have a few baby pekin ducks and 4 days ago, noticed that the runt was listless and limping, then followed by the mucous out the nose and slime out of it's mouth....2 days ago another one was limping....both died that night....now, have another one that is limping and becoming listless....any help??? Don't know where to find a vet.....

I noticed our baby duck spitting up mucous today as well. i do believe it just started. Where do you purchase the water fowl antibiotic? Do tack and feed stores have a supply. Also to the person yhat gave their ducks the antibiotic, you said they seemed better so how are they now. very worried about my babies!

Can Genny M tell me what she did because my baby duck is reall really really sick and it almost died but it didn't than god I need to know so I can do it please help

I just saw this, but I heard that if you use some apple cider vinegar (give them some straight via a dropper), it can actually help them, depending on what is wrong with them. If you started them out on medicated feed and withdrew it too fast, that can cause them to die. We lost some nice chickens that way, so we don't use the medicated feed anymore. We also had a bunch of adult birds die because the feed store accidentally sold us some medicated feed, which we didn't know about at the time, and it killed off a bunch of hens. Organic raw apple cider vinegar is supposed to be very good for livestock and humans too.

Make sure not to feed ducklings medicated feed. Chicks need amprolium to help fight off coccidiosis. Ducklings don't need this and can overdose on it because they eat much more than chicks. Add brewer's yeast to their feed if you're using a non-medicated chick starter feed.
