I have 19 RIR hens, well they will be considered hens in about 1 1/2 mths, anyway I have 3 that have poop infested butts.... I'm wondering if they are the ones laying the jumbo eggs, also how do I clean this, they are not the friendliest of my flock and it just looks hideous, I know they can still poop because I have seen them, however it has to be annoying to them as much as it is too me, any suggestions?
