Sweet Birdmanhey mrs p... im back finally...been super busy today
had a nice day....hope everyone else did....got the base on the four new coops done...tommarow I shall build walls, put wire up and put the doors in and then transfer the birds to the proper spot

No you just poor a lot of the dust on them after ruffling their feathers around and while your dusting if you have another person to help that's always nice so then they can hold the bird while you dust and I recommend wearing a dust mask because it is poison
your going to have to dust them for about 6 weeks to fully get rid of them maybe even longer you could have mites but by the color it looks like poultry lice you don't have too many chickens though so it shouldn't be too hard and you must dust every single chicken because I bet 100% your other chickens have them too even if it is only a few
