Hi. I have 5 chickens. I started with 3, but they are pullets & it will be a little while before they are ready to lay eggs. So, my friend gave me a mature hen. She started laying eggs here the day I brought her home. She laid an egg every day for several days. Then, I added another hen to my pin. She has a hurt tail. Since I don't have any mature roosters, my friend wanted her to stay with me so she could heal. She lays eggs every day, but the other hen stopped. She has not laid one egg since I added the other hen to the pin. Is there anything I can do to encourage her to start laying eggs again?
