Sadly we lost one of our 5 month old hens on Sat night. Friday evening her comb went grayish white, and by morning she was gone :( no other symptoms. Since then, we have notices that others in our (now) 8 bird flock have had mucky, soft green manure.
Apart from this they have no symptoms...
These chicks are 5 months old. It seems like it should be clear because they are pretty different, but the one that I suspect to be a male has never made a peep... I've attached pictures of both. I am new at this so I'd love any feedback Thanks so much!
