I have been watching various Webinars and a few months ago, I saw one about how to stop or slow down a single female bird from laying eggs. First, from what I remember, the vet said that it is hormonal. Then, the vet talked about why the bird gets hormonal and if the bird is healthy and hormonal. A healthy female bird who becomes hormonal and lays eggs has a few reasons for doing so.
The first thing the vet said was Diet. Then add humidity levels. Then add physical contact. I wish I had payed more attention to the program. I just remember that diet, etc was mentioned . There are foods that the bird eats that helps make the bird get hormonal. Restricting the bird's food will not be beneficial, but what the bird eats makes a difference. The humidity levels played a part and how much physical contact the bird has with the human, like tickling, hugging, etc.
People called in with questions and the vet was all over the place with answers. I hate that. I like to listen to lectures where the information is in an order.
I am going to look and see if I can determine which webinar I saw. I recorded some of them, but I think I didn't record this one. I will check.
I will let you know....sorry.
