She started about 10 days ago. I have no rooster so she is just going off instinct. But she is keeping the others from laying . They used to take turns laying in the same nestbox even though there are 3 of them. Now she sits in it screaming at them if they come into the coop. I tried taking everything out of the nest boxes so she could see the ground,I take her out 5 times a day to the other side of the yard with the other birds but she sneaks back to the coop. I'm running low on eggs because of her. My other birds are not laying in the yard as I have torn it up looking. She has everyone nuts as she walks around screeching and screaming. I wish I had some fertilized eggs but I don't. I'm about to make chicken soup.
