Hello! We have 25 hens. One of them is recovering from very bad mites. Some of them are 3 years of age. Others 2 and others 1. We had two roosters. They tore all of the feathers off our hens. We got rid of them. After the roosters left, our girls stopped laying eggs. This has been going for many months and we get 0 eggs a day. On very rare occasions we have gotten 1 egg. Someone told us that if we got a rooster again, the hens would start laying again. Is this true? Thank you!
