Did you change the way you manage your flock after this attack? IIRC, you were limited on the number of ducks you could have, is that correct? I remember the vet cost was considered on balance worth it because your husband is allergic to so many foods, but not duck eggs which he needs for protein.
Just wondering if culling the injured birds and starting over was an option? For $600, I think you could buy lots of duck eggs, even if you had to order them, until the new ducks started laying. Or were your options more limited?
I think the OP's duck will probably survive and do well with just home care. And if the duck goes to the vet, that's OK too. We all have different reasons for managing a home flock and most of us don't do it to save money.
It might well have been cheaper to cull and go without eggs. Had we not sought vet care, we would probably have lost our entire flock. Even the one less injured duck would probably have died of infection and loneliness. Starting over would have meant five or six months of no eggs. It was too cold to ship ducklings to our area and special ordering through our local feed store, which is how we got our Welshies to start with, took almost two months and the manager who was willing to do it had left.
We don’t live near a large metro area and duck eggs only occasionally show up at the local co-op and never in the grocery store. They usually run $5-6 per half dozen. My husband eats two dozen per week. We haven’t found any at local farmers’ markets, which are only open in the summer.
Starting over might have been less expensive, but the weather was way too cold to brood outdoors and we no longer had a room in the house available to brood in safety from our dogs. Our high temps were still in the teens and twenties Fahrenheit. I was still recovering from shoulder surgery and couldn’t bear much weight. We brooded indoors the last time and it was a lot of heavy work keeping the brooder clean and fresh. I just didn’t have the energy.
This was not a completely financial decision for us. The toll it takes on my husband to have his food choices even more limited is significant. He has food allergies to several staples of the typical American diet that take a huge number of foods off his table. In addition, he was supposed to have secured the ducks in their house at dusk, but had left them in what we thought was an adequately secured, roofed pen, covered in layers of ice and snow, while we went to church. He is very attached to each of our ducks, though I do most of their care. I know him. He is practical, but would have grieved their loss deeply. Again, not a completely practical financial decision.
Our duck pen is now thoroughly armored. We could still lose them to a tornado. My husband wants to put on a wood roof on top of the full hardware cloth currently covered by a heavy tarp. Not a day goes by that he doesn’t regale me with a story of the ducks’ antics. He broke his back as a teen and is in pain all day, every day, so having the ducks cheer him is worth a great deal. He still works full time to support our family and I am at home caring for our son who has special needs.
Money doesn’t grow on trees for us, but it isn’t necessarily the driving force behind every decision, either. That’s why I posted what our total vet bills came out to, so the words “not cheap” would have more practical meaning.
