I went out to feed chickens and pigeons today and found one of my summer babies outside the aviary. Yup you guessed it, I found a hole. In the corner. I could not catch him and didn't know how he was going to get back in. Certainly he wasn't going back in that little hole. So I had to make a big hole for him. The aviary cloth is in two parts and tied together with plastic ties so I cut some off and opened it up. I locked everyone else up in the bunny coop so they could not escape too. WHEW! I back out an hour later and my baby came back. My aviary Others locked up OUT! Made a hole for him to get in IN Caught one in flight.............All birds are set free now and happy.
