I am new to the forum, but not to poultry. Two weeks ago we received our first batch of ducklings for the year, 60 Grimaud Hybrid Pekins. After a couple losses the first day, and accounting for extras sent in the shipment, we had 60 vibrant ducklings growing wonderfully.
On Sunday morning (two days ago), there was a duckling suddenly dead. I figured it was just one of those things. Then yesterday (Monday) evening, there were two more, plus another two with difficulty walking. I separated those two for the night in a small box within the brooder. This morning one was dead, and the other had gotten out of the box, and there were another five ducklings dead.
Throughout the day today, they have just kept dying, seemingly preceded by lameness, then general immobility and floppy necks, though some have died in such a short time span that they either went through these symptoms really quickly (like, within an hour) or skipped them altogether. All told, we've lost 21 ducklings in the past 24-ish hours.
When I find lame birds, I've been separating them by putting them into a box (the box they shipped in from the hatchery) in the brooder. Some of these eventually jump out and run around normally, and some die. The first step of lameness seems to be walking back on their hocks, for what it's worth.
I can't for the life of me figure this out. It's as though a switch was flipped and the ducklings have gone from great to dead. The symptoms are somewhat similar to botulism poisoning, but in the bit of reading I've done most (if not all) cases come from birds outside, not birds in the brooder. There is nothing decomposing in their environment, anyway.
Their feed is a general-purpose poultry feed, custom-mixed by a local mill, consisting of corn, wheat, oats, sunflower seeds, alfalfa, and soybean meal, plus a poultry (laying hen) mineral mix. The mineral mix isn't ideal, but we used it last year with no problems. We then mix in nutritional yeast to up the niacin content. We thoroughly wet the feed, which as I understand can be a botulism concern, but we've been doing that for a couple years now without issue. In any case, the wetted (soaked, really) feed lasts for three days or so at this point, so it's not as though it's rotting.
Any thoughts?
