Hi everyone! 
I recently got more chickens and have already encountered something I've never seen before. My Silkie hen had a very large beard and recently it turned to dreadlock/calcified clumps. I examined her and found a few mites, so I bathed her and checked again. After not finding anymore bugs, I decided to try and cut the clumps off because they were clearly distressing her.
Once the clumps were cut in half, the composition of the clumps did change and I found a few more bugs. Now I'm concerned that seven dust won't be enough to get rid of these.
Any advice? I attached a picture.
