Hi I'm in NSW Australia and we've just got 2 new little chicks (Star and Flower) to add to our brood of 7. I'm really concerned about them as we have had 6 of our chooks die in the last few months. I think they are pretty unhealthy even though they are free range and are fed grain and kitchen scraps with fresh rainwater and have no predators except rats. I dont want to lose these chicks and have been recommended to feed the chooks fresh wheatgrass juice. Any other suggestions? What sort of vitamins should I give them - what are they called? And what is the name of the mite powder someone suggested getting? And can anyone recommend a way I can get all this stuff online? We have no shops here where I live and everything has to come by post. Thanks!!
