Hi, our new pullets- mostly this one in photo - are muddy (dry) due to coming from a farm that was terrential rain while they were being caught. They are dry under cover but the mud hasn’t come off. I don’t want to wash them as they are new and don’t want them to be afraid of me. Is there anything i can do - they aren’t out in the rain - maybe this is a natural option - but won’t happen until they have intergrated with existing flock, so not for another week. Is this the best option?
