Found our RIR - Jo Jo this morning. She must have passed last night soon after she went in. Almost like she fell off the perch. No trama, no discharge. She was a Spring Pullet last year. We have lost two others to predators, but not one like this. Our last flock introduction was in August and nothing particular has changed with the weather this week. I am stumped. She had been a late layer, but usually produced daily since. It has been two or three days since she layed. Ideas? Everyone else seems healthy and fine this morning.
