I have 15 full size cochins and they all are healthy as far as i know, i noticed a few weeks ago that a few of my hens had poop bottoms which is common for them on occasions but usually cleans up on its own shortly, but after checking almost all have it now. I know i should give them bathes to clean them but its 40 degrees here and bringing all 15 in just won't happen could anyone tell me could this be happening to them due to a sickness or maybe worms. Just find it odd not one had it then suddenly they all did even my 2 roos. Maybe the cold is making it freeze to them verses dropping on the ground?... They all are eating drinking and acting just fine.
