Lisa, I don’t believe the parents feed them much, if at all, the day they are born. I would let the wren guard alone for now. If by tomorrow you don’t see them being fed, they maybe you could take the guard down, but if mama incubated them for 14 days with the wren guard on, I don’t think she will abandon them now. I know it’s hard, but be patient. The wrens will toss out real small babies in a heartbeat if they get the chance. Let others chime in here with their opinions, and congrats on the hatch, for now anyway. P.S. Just saw your other post about seeing mama come out of box – take a deep breath now and enjoy them!
