Friday I bought a flock of 6 rumpless araucana chicks and their mother hen from breeder Nancy Utterback. The chicks are 9-10 weeks old. They all have been in the coop since Friday, and I am hoping to let them out for about an hour this evening if I can get home from work in time. Their run is in part of the yard that has not had anything in it before (no other animals) and is mostly grass and a small dirt area. It also butts up against the barn where sparrows used to roost under the eaves and poop all over the ground. This was block off from the sparrows in June. We have had some wet conditions lately, the ground is wet and that combined with knowing sparrows used to poop there has me worried about coccidiosis. I have them on medicated chick feed. Is that enough to prevent the disease? I also have some Corid, would it be okay to start them on that or would that be overkill? Anything else I could do to keep these kids healthy?
