Should I just assume our girls have lice? They're nearly 5 months old now, and they've been outside for at least the last couple of months. I don't see any real signs of infestation - I think - they're not scratching or shaking their heads, that I can tell, and their feathers are incredibly shiny. But I was looking at one's vent and noticed one white clumpy thing (smaller than a grain of rice) stuck in her fluff. Could this have been eggs? It seems from reading various threads here that lice and mites are pretty much a given with chickens . . . am I right? And if so, who votes for DE, Sevin or Permethrin - and why? I'm really paranoid about using chemicals, but I also hate bugs!!
