I have had my first group of ladies for about 3 days now. They are about 6 mo old red buffs. They seem to be doing great- laying, eatin, drinking, playing with each other. However they're back ends are strung with poop all in the feathers We Bought nutrena good food and haven't given them any treats other than mealwo scratch. The poop on ground looks normal? How often do you guys have to bathe (or clean backsides) of your chickens? Is this normal or could the poop be slightly different since they are adjusting to their new home? Thanks!!
