Guinea Hen in Morning?

Hi! Not sure if another bird can mourn the death of another one so I thought I would reach out to see if anyone else seen similiar things.

About a month ago, our RR Rooster died. He was getting old and starting to show his age and honestly, I just think he died of nature causes. We have one guinea hen in our flock that has always thought she was a chicken and her and the rooster were buddies. Since his passing, she is non-social with the others. Stays outside even when it is dark. Tries to get into smaller areas of our hen house at night instead of the boxes and on top of the boxes like she had in the past.

She is still eating but her personality just seems to have changed since he died. She was definitely social but now, not so much. Any thoughts? I feel so bad for her.

Yes they can mourn over a lost of a friend they get attached to.

I have seen this with my birds as well. I had bought 2 RIR and 2 EE as three day old chicks. They were very close and the 2 RIR were inseparable. One day while free ranging a predator got hold of Sissy, one of the RIR, and left a trail of feathers leading to the creek where I found her wings. Even though they witnessed the attack Purdy would look for her and call out to her constantly. At night she would frantically look out the door and then look at me as though I'd forgotten someone. She would then jump down, look in each nesting box, look behind the food and water and then proceed to stuff herself into a corner of the coop on the floor. I would have to pick her up and hold her for a while. I'd stroke her head and face with one finger and talk to her softly until she was completely relaxed and then put her back up on the roost. It always hurts to lose one but in my opinion it hurts even more to witness them grieving one of their own. Give your girl lots of love and reassurance . She will come around in time.
