Putting this here - hope it's the right place. It's not an emergency or injury but it is health related. 5 hens. Seemingly happy, healthy, laying, eating, love treats, have been wormed, don't fight with each other. But for the last few days I've seen some poo that issssss ummmm not loose, not firm but it's brick red. Not all the hens just the BO and 1 of the EE's. Something to worry about? I'm thinking that maybe I've given them too much yogurt or something.... ????? Thanks for any input.
