Hi,I hope I get help from here because I am getting more stress than my chickens. I have 20 chickens they run between 10 months to a year. Plymouth Rock leghorn Rhode islan Amerucana Ancona Catalana and two more breeds that I don't know. I feed them during the day 20 % protein and crack corn around 5 pm when they are going to bed. They have heater water . I used to put this dark brown vitamin in the water that in IFA recommended. I put a white light out side the chicken coop at 4am and I'll put a heat light inside when is to cold. They were laying just fine , I was getting between 6-9 eggs a day. From one to another they stopped. In IFA they though that they might have mite so I bought the powder for them and I did the treatment ......that was over two weeks ago. Still no eggs. I took the red light out , still no eggs I let them run around my backyard because will all the snow and rain they have mud, still no eggs. I took the white light out and still no eggs. Then I have this neighbor who's chickens have the red light all night and they run in the backyard with no 20% feed and no crack corn in the evening and they have eggs just fine....... so what am I doing wrong? I get maybe couple of them would stop , but not all of them and so sudden. I was getting eggs from all of them now I get nothing. I get very upset because I don't know what else to do!! I thought would be easy job, clean, feed and get eggs .... well I clean, feed and no eggs. Any advice??
