I'm wondering if anyone has ever tracked where their chickens go to lay eggs? We have a hen who is only one year and is no longer laying her eggs in the nesting box. I've examined her and she is healthy. The only thing I have done differently is clean out the coop. She has done this in the past but I found her "nest" pretty easily. This time it has been almost three weeks without any eggs in the nesting box and I've checked everywhere on my property. I want to use a gps tracker to track where she goes throughout the day and how much time she spends in every location. Does something like this exist? Has anyone done this before? I'm assuming there has to be some kind of gps tracker for the legs that is used with pigeons.
