Hi Opa, Spring will be upon us soon here in Londonderry (NSW, Australia), and this "crazy chicken lady" is becoming very clucky. I have just started looking for some ideas for a chicken tractor as my brother has kindly agreed to build some for our family. I have read some of the posts on this thread, and intend to show my brother what you have done, and see if we can incorporate this idea into the tractors. We will only need two nest boxes for each tractor. I think I will go with the idea of a block to create the fall away, so that when they go broody (fingers crossed,) I can remove it and place the eggs for them to sit on. Any advice/suggestions from anyone would be appreciated. Thank you for your dedication to helping others Opa. Much appreciated.
