Hi, I got a couple of new brahmas a couple of days ago. 15 weeks old. I thought one had a scab on its nose yesterday, but today the nostril was completely covered. I was able to flick it off and realised it was a bit of dried discharge. Is discharge always bad? Could stress bring it on? It's 30c + here today (Australia) and I'm wondering if it's a bit too much with moving in to the new place etc.
