We bought a replacement hen who’s flock was killed off. She was the last one. Her name is Ellie. She is the hen in my profile pic.She’s a Easter Egger. Person we got her from sold her so she could be with other birds since she wouldn’t go outside.Raccoon got in and killed all my chickens but one, one night. Lucky, the one that survived, would not come off her perch until I got more hens. That was the saddest hen I have ever seen. She was a year old and the new hens I got were 18 weeks but once they got their pecking order together, they have all done well. They have gotten used to you being their Mama, please just get some to go with the ones you already have. Chickens are social animals
and band together well. They will get over their loss and adjust better with more chicks.
