My chickens are molting and havnt layed any eggs in at least a month. They rarley leave the henhouse (because it is very cold where i live) and They dont eat or drink as much as they used to. They hardly touch their food. Is there somthing Im doing wrong? Iv been giving them a higher protein food but they still will not eat. I dont want them to die and Im cancerned then havnt layed in so long. Is this normal?
