Welcome To BYC
I'm sorry about your chicks.
Can you post photos of them and their poop?
How old are they?
How long did it take for them to make the trip to HI?
Do you have any pet shops or feed stores that carry Corid?
@ChickNanny13 any ideas?
Do try to find some Corid if you can. In the meantime, try giving them a wet soupy feed made with buttermilk or plain yogurt with a little water.
The one singular place I've found on our island does carry it, but is out of stock.
Every single other feed/pet/country style store employee i talked to had no clue what I was talking about.
Apparently it is incredibly rare here, even tho the soil is almost always damp. (200" of rain minimum per year where we're at).
The entire neighborhood raises chicks/chickens.
They also roam feral.
Never once has anyone on my street, in my social circle, or in my town has even heard of cocci.
I work in fine antique restoration and brought home several very fine-tipped plastic 'syringes' usually used to administer glues with precision.
We've been using them to administer food and water.
Unfortunately the only photos I have are of them either dead or dying, but I will post if requested.
Only took the dead photos just in case Murray McMurray requires them for a refund.
(It's not about the money, but the principle. We're both extreme animal lovers and continually digging graves is breaking me down in a big way.
((Sure, you should expect some deaths while homesteading but this is very different from anything we've encountered))
The chicks were shipped day old, according to the paperwork, and were also supposedly vaccinated. I'm new to chicks and chickens but my S/O is a generational farmer and has never experienced this here on the islands
