Hi!
Many Grey hens lay eggs, especially when they reach their teen years. They are infertile and it does NOT mean the bird wants to be bred. It is a hormonal thing that is generally brought on by something that we pet humans have done. What I mean by that is that we give them boxes to chew, paper bags to hang out in, little stuffed animals to sleep with and so on. You can compare it to a single person. You don't feel those sexual urges until something triggers them, such as meeting someone exciting... or something like that.
The egg-laying process is hormonal and we must allow the body to go through the entire process. If we don't, they could keep laying eggs and get sick from the loss of calcium. Therefore, when your pet hen lays an egg, you will need to let her go through the process. That means, when she lays a second egg, please set up a nest box in her cage. That can be a cardboard box with a comfortable rag in it or something. Allow the bird to sit on the eggs or at least have the nest box in the cage for about a month and then throw it away. Once the body has laid eggs, it needs to go through the process of being able to brood (sit on the eggs, or at least think that she is).
Wild greys lay 3-5 eggs. So, your baby will probably lay more over the next few weeks. When it is for the first time, she may lay only one or two. The process is generally traumatic for the bird, so please watch over her closely and make sure she is eating.
Please keep us informed.
Blessings,
