Can I have some advise please. She is 3 yrs old. Has been laying eggs, not fertilised. Sat on them till she came off them. Started laying eggs again, I took away nest box as she had by then started plucking. Took her to the vet, he said she looked healthy, it was possibly hormones. She eats okay, has veggies and everything in her diet. But is plucking like mad. Any suggestions please. She has a mate but they are very close but don’t mate with each other.
