Hi everyone. Normally all 4 of my hens bolt out the coop in the morning when I let them out. This morning one of my hens (2 years old) has stayed inside. I"m a new chicken owner and don't really know if this is cause for alarm or not. She looks normal to me. Her feathers look normal. I don't know what else to look for. I pet her a little bit (which she usually lets me do) and she didn't make any sounds, which is unusual. Should I get a vet to come out? It's expensive but I can do that if it's necessary. I just don't know if I should wait and see if she comes out or what else I should do instead of getting him to come out. Thanks for any help.
