How worried should I be about Cocci?

Right now I have 14, 6 week old chickens, 4, 6 week old ducks and 2 11 week old ducks...
I have not ever fed them a medicated feed and no one has come down with Coccidosis that I have noticed and I watch my birds alot.
I do keep a antibiotic on the farm in case I notice anyone coming down with anything but have not had to use it.
I now have 25 new Jumbo Cornish chicks coming and while they will not be housed with my layer birds I am starting to wonder if I should be really worried about an outbreak of Cocci?
Does anyone know how long those organiziums (omg horrible spelling, sorry!) can live in the ground?
I do live on a 300 year old farm that was once used for poultry; turkeys and chickens. The property was last used for birds about 20 years ago before now, though the old farmers kept the birds in the 3 story barn/carriage house and we doubt that they ever had access to the outside (sad huh?), they were meat birds.
Now, I know some things about Coccidosis in dogs and cats but do not know if the dog strain is transmittible to poultry?
Show dogs were also raised on my property at one point and in dogs, once they contract Coccida even when it's cleared up, in times of stress or illness they can release the "bug" in their waste. I have 3 dogs of my own, two of which are confirmed as being immune to Coccida now but who can also still produce the "bug".

Anyway, what should I be doing at this point to make sure I do not run into a problem with this? I know cleanliness is a big thing. Right now my 14 chickens are turned out with my 6 ducks in an 8X8 pen (I know it's small but it's only supposed to be for the ducks!) while I wait for my DH to build the chicken coop and pen, hopefully this week if we don't run into any more health problems of the human sort (everyones been sick, that's why the chickens are in with the ducks, they got too big for their brooder but had no where else to go but in with the ducks while we got better and build the other pen!).
I worry with how dirty the ducks are that with all the poo building up in there they will come down with it. I have been letting the chicks and ducks out to range whenever I can and raking the pen to clean it up a little, I've even put down grass clippings in the bottom of the pen for now to keep them off the poo. I really should have put something down in the bottom of that duck pen before I put the ducks in it! Hindsight is 20/20... I need to put sand or something down in there, they are so messy!
In the meantime does anyone have any tips for me on how to keep this pen clean when it's becoming a mud pit?!
Sorry for the loooong post and all the questions!
Thanks for reading!

 

Thank April

 

Ok, great info Greyfields, but what do you suggest I should do?

I hadn't thought that the meat birds kept on the farm prior had been kept indoors because of a high chance of them getting sick, we figured they were just very inhumane farmers due to the discusting conditions our barn was in lol

 

What I'm finding really interesting is that NONE of the RI and MA feed stores sell medicated chick/chicken feed!!! This seems nuts to me if this is a problem in my area, no?

Before I got my laying chicks I called 10 feed stores and none of them sells a medicated feed. We only have 5 feed stores in RI altogether. This has me scratching my head.

We also don't have a vet who will see livestock chickens, if I want my chickens tested or treated for anything at a vet I have to bring them to a regular pet vet. *again scratches head* I have called three vets locally so far asking for reccomendations for livestock vets to keep on hand, got number for several, called them all and got told they only saw large livestock!

Now I'm getting frustrated...
I think my husband will kill me if all 25 of these birds drop dead on me.

Can you eat birds that have been fed medicated feed anyway?

Having medicated feed shipped to me would cost too much.

 

I know why, it's all here in Rhode Island!!!!!!

Seriously, we have tons of it. I don't understand why.
It could be that the high majority of people raising chickens here for eggs and/or meat are in the organic/high quality movement and don't want anything in their feed.
Same thing with vegetable and fruit gardening here, there are a TON of organic fetilizers and plant foods on the market at home depot and TSC but only one small section of things like miracle grow, etc.
Having livestock here isn't exactly common. Keep in mind that you can drive from side of my state to the other in less than an hour!

Just not too sure what to do now. I have these birds shipping out on June 4th. I guess I shall just have to "wing" it and see what happens.

I have them going into a brooder in my garage and then am going to build a chicken tractor for them.
I read somewhere here that someone recommended giving small chicks little bits of exposure to the soil starting at 3 days of age to help them build some immunity, how do you feel about this Gryefields?
I already know I won't deal with these birds again and I haven't even gotten them! lol I'll do a different type that is more hardy to disease in the future.

Makes me want to put these chicks in a glass bubble!

Thanks bunches for your input Greyfields

I can't breed these darn things, nor would I want to. I'm not sure if I should eat anything that's been eating medicated feed so I'm leaning away from that, and ditto if they do come down with it and need to be treated. I guess I shall be eating the survivors and burying the ones that kick the bucket. You live, you learn!
