I just noticed very small black dots on 2 of my hens' combs. I thought it was dirt because it's been raining and it's muddy here. But when I picked one it bled a bit. The other 5 are perfectly fine and no sign of spots. Everyone is acting like they feel good. The two that have the spots are the two that are laying! I haven't brought in anyone new and haven't been to any other chicken yard. We do however have some new chicks but their paths have not crossed (babies in the house still) and I am careful about using chicken shoes, washing my hands, etc...Could this be a mild case of The Pox? This time of year? Should I go ahead and vaccinate the babies at 6 weeks? Is it hard to do? Crap.
