We are just starting out with chickens and are using the medicated chick starter for our chicks. I would like to use the unmedicated starter next year and have been trying to learn as much as I can to prepare myself. The learning curve is quite steep and the new information is overwhelming at times. In this discussion on Antibiotic Resistance on the forum at www.the-coop.org, D Cavany says, in his third post down, (hope I counted correctly) that you can vaccinate your chicks for cocci by mixing some chicken poop (from older chickens) with a quart of water and giving this to your chicks. Repeat this treatment at week two and again at week three. On backyardchickens.yuku.com, there is a discussion asking if anyone has tried the cocci vaccine that is available. In it, Wes in TX refers to the same treatment of putting poop in the chicks' water (post #5). D Cavany says, in his post, that he has had good success with this method. Has anyone else tried this method of vaccinating your chicks? What was your experience? Also, and I know that this is kind of dumb, but would you just put a handful of week-old poop/litter in the water? I assume that I would stir or shake and strain but I am concerned about the amount of poop to use. Here are the two links to the respective conversations: Antibiotic resistance Has Anyone tried the Cocci vaccine? My searching for more information on Cocci lead me to this page as well: Dealing With Coccidiosis In Pastured Poultry Now, all the way down near the bottom of this page, there is a section for treatment and in it, there is a recomendation of using raw milk as suggested by Jeff Mattocks of Fertrell. Has anyone tried this as a treatment? What was your success using it? Just trying to get a better understanding of what the risks are to the various options and approaches to cocci and chicken husbandry in general.
