Went to a chicken class last night. I received a book http://www.amazon.com/s/ref=nb_sb_s...ht&sprefix=The+backyard+chicke,stripbooks,285 I enjoyed the class very much. I learned why my chickens aren't laying, not enough light, days are too short in Idaho winter. So if I want eggs during winter I need to supplement light. I was also told to change the size of my roosts for winter to a 2x4 with the 4inches on top. Reason is to help keep their feet warm during the winter. So when they sit, they cover their toes with feathers. I took a lot of notes and look forward to reading the book. She also taught us how to make an inexpensive water heater with a popcorn tin, light, and metal water bowl. I will post my thoughts of book when done. Have a great chicken day!!
