We bought a few chickens a few months ago and a duck was included, the previous owner wanted her to stay with the chickens since they've all been together. Well, since we've had them our Isabella hasn't laid ANY eggs. They're still in a temporary pen with only some nest boxes about 2-3 feet off the ground. Do I need to make her her own little nest box closer to the ground? I don't know why she isn't laying. Any ideas?
