I've been raising Bobwhite quail this year as a hobby and as "pets" with my husband and kids and and things have been going pretty smoothly until today when one of them escaped and disappeared. This is my first time raising quail so I'm not sure what to do in this situation; will it come back? What can I do to encourage it to return to the pen? It happened this evening around 5:30pm...I heard the quail making a lot of noise so I went over to the pen and discovered that one of them (a male) was loose outside the door to the pen, calling and pacing back and forth in front of the wire while the rest were inside calling back to him. I began to slowly approach him but he quickly ran away down the bank into some bushes. At this point I went into the pen (it's a walk-in wire flight pen with a hutch at the back that they perch and sleep in) and quickly herded the rest of them into the hutch and closed and locked it. I then quickly checked the flight pen but couldn't see any way at all that the quail could have gotten out...I still don't know how he did. After this I went and got a whistle I bought that imitates a Bobwhite call and went out near the pen and whistled with it; the loose quail was nearby and would call back but I couldn't see him. Eventually I found him on the other side of the fence in the neighbor's yard, trying to get through to the pen on the other side. I went around the fence into their yard and tried to herd him back across through an opening but when he saw me he flew about 50 feet away and landed in some branches by a pond. I went back to the door of the pen and whistled some more and he would call back every time but didn't seem to get any closer. At this point my husband got home and went into the neighbor's yard toward him but it was too dark to see anything. I kept whistling, but starting when my husband went over there the quail stopped calling back. I stayed out there for another hour or so whistling but no calls back since then. I came back out with my laptop and played a video of bobwhite calls through some speakers and the bobwhites inside the hutch went crazy over it but still no response from the one out there loose. I gave up and went inside once it started to rain. I left the door to the pen propped open with food scattered around on the ground in and near it but even if he does come back I'm not sure why he'd stay in there and not just walk right back out the open door again. Due to the way the hutch is designed, the rest of the quail can't be seen from outside unless the door is open (which I can't open or else they'd all be loose too) so he would be coming back to an empty pen which I'm also concerned about. My kids are pretty broken up about it since they hand-raised these birds from eggs but I'm not sure what else I can do. Any tips or advice would be much appreciated!
