My rooster passed away about A month ago. My hens were very scared for a few days but I was able to get them to feel safe around me again and eat out of my hand. They are perfectly healthy they just seem... sad. I'm not really sure how to explain it but I think they miss him a lot. My hens do all the normal chicken stuff, but they're quieter now. they aren't making their normal happy sounds whenever they get treats or dustbathe. I wouldn't be that worried but It's been over a month now
