Hi! My name is Kathleen and we are new (very new) to chickens. At first we bought 6 red sex links from TSC. Learned my lesson there. Then after lots (tons) of research I decided to go with our neighborhood feed store, they have all their chicks immunized and get them from Townline and Mcmurray hatcheries.We live in Michigan. So two of the sex links have died. We have kept the others separate, just in case. We have two Bkack Australorps, a Buff Orpington, a Dominique, a Buttercup and we pick up an Aracauna tomorrow. We actually just got the Dominque and Buttercup today. The Australorps and Orpington are two weeks old. The sex links are about 4-5 weeks (and HUGE!). I don't want them anywhere near my special breeds until I know for sure they are free from any disease. So the reason I am writing you, is because it looks like you have some of the similar breeds. Just wondering if you have any tips...Thanks!
