Recently, my a fox had broken into my coop and killed four of my six 8-month old chickens, and thankfully two were able to escape. Out of the two, one of them hasn't laid an egg since the accident. I know that this can happen if under stress, but I'm worried she may be egg bound because the other day she wouldn't leave the hen box, her butt constantly moves, and the other day she pooped liquid green. I'm currently sick with covid and can't go to the vet, so does anyone possibly know what this could be, and how I can help her? She refuses to go into the hen box sometimes and I just want her to feel better and live to another year.
