This chicken is a 20 week old speckled sussex. I have two chickens and they just started to lay 3 days ago I have gotten 2 eggs and don't know from which chicken. One chicken has some yellow scab things on her and it looks like dried egg yoke. But, I don't know much about chickens. What is this??? Is it a sickness or did she (or he) get a hold of what would have been my third egg?? If so what do I do about it?
