What I’ve heard is that you can (it’s a little gross) to be sure that she egg bound, first separate her from the flock, then glove up your hand, apply Vaseline or something similar, and press a finger into the vent. If she is egg bound, you should be able to feel an egg. Although sometimes soft eggs get stuck higher up. You can also feel her abdomen to see if you can feel an egg. If she is egg bound, put her in a dark room and try and keep it fairly quiet. You can give her baths every few hours, (if you have a laundry room sink or something, you can use that) you can also give her calcium, 500mg (if you just have human calcium, that works.) anyway, hope this helps. I’m really not very good with this, but this was the information we were given when we suspected our hen was egg bound. (She sadly passed a few days ago, we think it was actually reproductive cancer)
