I have no problems with my 7 buff orps, rir and my cochin roo. But my 8 Delaware Blue hens and 2 EE's are always leaving the yard! They fly up and over the fence and out they go! I have tried locking them in and they just fly up and out. I am short on money so at this point, covering the run isn't an option for at least another 2 weeks. They are at laying age but I haven't gotten any eggs yet (here in the coop) I am worried that they are gong to start laying out in the bushes and not learn to lay them here..plus I don't want babies to magically show up! How can I teach them to lay in the coop if they won't stay here??
