My condolences,always heartbreaking to lose a beloved pet. Yes chickens do experience stress/depression/sadness when one of their flock mates die. They were probably calling for her and cannot understand where she is,so heartbreaking.
When we as chicken keepers know the emotional attachment that chickens form to each other and to us,and that there is definitely more to these amazing creatures than what the rest of the world realizes or gives them credit for.
