You have to get them tonight if possible. Use the night as it is by far the best. I had a spalding hen get out a couple of weeks ago and didn't see her all day, come evening she came to her fellow peas calls and I found her roosting on the top of a run. Only one who ever got out since keeping peas and I got 50+. Get a ladder climb up and slowly reach up and grab them firmly. You would be shocked at how docile most are when asleep or its late. Do not wait till morning, there is a chance of flying off being new and all. Having the other birds should help keep them around. I use the night to get close and check health of birds. I can often walk right up and lift them off a lower roost to check weight. If you have a net, use it to catch them if the reach is a little far.
Wannab are the ones inside the pen females? and the ones outside the netting males? In my experience the male wont leave the gals! The females might stray if they get out but my male would roam around but would leave the property while his lady was in the pen. It was when she got out that they strayed from home.
Yes Near Pittsburgh Pa...But I have Ideas For her....She needs to get them before or at the break of day...Also she should find out if the person that had them had a routine or a call or saying or a can or bucket of corn to shake something to tell them there is food Ect...
