A few of the responder's mentioned mites - thanks for the heads up because yes either the new chickens brought them in or the birds did (that are able to fly through the dog pen fencing). A week ago, I shoveled all the bedding out of the coop, took out the nesting boxes and everything that was not nailed down. Power washed from roof beams, walls, cement floor with a mixture of dawn soap & water, then rinsed everything well. After all was dry, I put down food grade diatomaceous earth & new bedding. Also put diatomaceous earth in the dust baths (they have on in the run and one in the yard). Today as I was collecting eggs & cleaning
Will be power washing the coop again tomorrow - is there anything else I can use that will get rid of these mites.
thanks in advance for your advice
