Scaley leg mites and ivermectin in the U.K.

Hi fellow chicken lovers. We have a new hen with scaley leg mite.

We’ve tried a scaley leg mite spray but it hasn’t helped and to be honest it’s ballache to apply as it has to be done every 3 days for 10 sessions. Our girls aren’t particularly friendly and aren’t easy to catch (impossible) during the day so the only time to do it is at night.

I’ve been reading about ivermectin but in the U.K. I can’t get a paste without a prescription. I can get ivermectin tablets so was wondering if anyone has ever crushed a tiny tablet up and given a very small dose to their chickens? Any advice?
