Its that time again. Lots of pets need regular worming and chickens are no different. In the case of our feathered friends, they need to be wormed every 6 months. We did them when we first got them, and time has flown.We use Flubenvet. You can buy it at places like Countrywide and then its just a case of spiking their feed with it for a week or so. Since our enormous feeder holds over a weeks food for our flock anyway its a case of taking what we'd normally put in each weekend and adding the requisite amount of drug - in this case about a scoop. Simple.
