I had a run in with coccidia this summer and had many calls in to MSU. A couple interesting things. First I was told new studies show it isn't so much the soil that keeps the oocysts alive but that earthworms are carriers. So much for getting rid of them! Second you can do immunizations but they are not recommended for birds that will be in contact with the soil because being exposed will do the same thing if they are on medicated feed or a coccidiostat. Also there are 9 varieties and there is no cross immunity. Bringing in new chicks isn't a problem as long as you feed medicated feed or a coccidiostat, however I have heard lots of arguments both ways for selling your birds after they are exposed. The vet told me "most already have it" but I think a responsible seller has to disclose they were exposed and let the buyer make the call.
Oh - also that it is very resistant to disinfectants. Another great web site the MSU vets recommended for information is http://ag.ansc.purdue.edu/poultry/extensio.htm
