Hello, Concerned chicken mommy here hoping someone might know something about this potential problem I found today. I noticed today that one of the eggs I collected was speckled and that the speckles were upraised- obviously not a part of the shell coloring. So, I thought that this was odd and so I tried to wash the speckles off, thinking it was maybe dirt- really just wondering what the heck it was. Well, the speckles did wash off and left a reddish pink oily residue (very lightly) on the paper towel that I used to dry the egg off with. For you experienced chicken people, does this sound like a serious problem to you? It seemed the speckles were encased or had dried onto within that protective residue in which eggs have- I don't know what it is called but it helps protect the egg/chick to grow inside. (This protective encasement that I am talking about is clear and not really noticeable once an egg has been sitting around for a while.) Could this be mites or lice or some other problem? The chickens seem to be fine otherwise but then again I am a newbie and I am realize I may not be as experienced to notice something wrong. They are active and eating as well as they ever had. I would appreciate any suggestions... Also, can anyone recommend a really good in-depth book about chicken ailments and treatments? Many thanks in advance!
