Egg bound?

So, I heggs a standard coop we ordered from Tractor Supply that I built a larger run for. The only part outside the run is the nesting boxes to access the eggs. We've never had predator issues. My daughter went to check for eggs and her favorite bantam was sitting in the most commonly used box. Not sure if she laid or was just sitting on the egggs or preparing to lay. She's not a consistent layer at all. She's a loved pet more than anything. My daughter closed the box and went in the house. I was outside and I hear my neighbor yell at the other neighbors dog and yell for me that he had a chicken. I ran and my heart sank seeing Peaches on the ground in a pile of wet ruffled feathers. I carefully picked her up and checked her over. Thankfully no blood but I didn't know how hard he bit on her. Our best guess is he is tall enough he could push up the nesting box lid and scared her out, then grabbed her and was headed to his house. I called for my daughter and she gathered her baby up and went inside. Keep in mind she held this chicken for hours as a chick, and has spent hours more with her above the rest of the flock. She's the only one trusted to free roam because she won't leave my daughters side and even perches on her shoulder like a parrot. I prepared a hospital cage but if my daughter moved, Peaches seemed to pant more due to shock. I wrapped a towel over both of them and she laid with Peaches for a couple hours until she relaxed. I checked her again and she seemed to be recovering. 3 days later and she seems normal. My only concern is her being egg bound. She's acting normal, tail up, dry poop. What worries me is she makes the "announcement" clucking like when they lay an egg or a loud almost crowing noise, but no egg. We've kept her warm, warm water soak, liquid calcium. I don't think I feel any egg near her vent. Is she ok to put back with the flock?

If she is eating, drinking, and acting normal - I would return her to the flock. The longer she is away the greater the chances of fighting upon reintroduction. The cessation in egg laying is most likely a result of the dog attack.

Ok she's back with the flock. Took some fresh greens with us and in she went. No one batted an eyelash at her return. She went and picked the other two bantams on the head once each as if to say, "I'm back and I'm still queen of the littles." They relinquished their place to her. Life back to normal for them. Thanks for the reassurance. Being my daughters favorite baby I was super scared for her.
