Yes, give her more calcium, another Tums. You are not going to hurt her with this, it's short term treatment, calcium issues arise from long term use of too much. If she is having trouble passing something, it will help. I suspect this is some kind of reproductive problem, but trying the...
I don't think the garlic and honey drink would really help. And garlic can be toxic in too large of amounts (chickens are very small). Do you have any antibiotics on hand? Old leftover human ones?
How is your hen this morning? Did she pass anything overnight and has she pooped? If so, what does the poop look like?
Do you know when she last laid normally?
I used the 10% orally. Dosages I've used are:
10 mg per kg of body weight 2 times a day for 5 days (0.1 ml per 2.2 lbs of the 10%)
15 mg per kg of body weight once a day for 5 days (0.15 ml per 2.2 lbs of the 10%)
20 mg per kg of body weight once a day for 5 days (0.2 ml per 2.2 lbs of the 10%)
If she were egg bound she would already be dead. When a bird is truly egg bound they cannot pass droppings either, they don't live long that way. It's much more likely that she has some kind of reproductive problem. The mass you feel could be infectious material from a condition called...
I do not think Corid would work. Corid is an anti coccidiostat, for coccidiosis, a parasite, not an antibiotic. My concern is that it's infection from the injuries. Externally I cannot see anything in the pictures that looks concerning, but I don't know what is going on inside, if there is...
How old is she? Do you know when she last laid? Is that ice cubes in with the egg?
Based on the dropping pictured I would say that something is going on, doesn't look normal. Do all her droppings look like that?
If she is ill, and thin, she may not be able to maintain body heat well, so I...
At this point I would say shipping stress. Some of them don't survive it. Doing what you are doing, keep it warm, give it plenty of fluids, give it time and see if it rallies. I have on occasion put them in a neckerchief/scarf around my neck, like a tiny hammock, with them resting on my upper...
Try some scrambled or cooked and chopped up egg. If she's not eating that would be concerning. What do her droppings look like? Do you have any antibiotics on hand? Amoxicillin would be good for this, to make sure there is not any infection that's been missed. Also, if you haven't already...
As long as she can hold her own with the flock, she can go back. If she's at risk of being further injured, I would wait a bit. I would for now, do it for shorter periods when you can supervise, so that if something happens you can intervene. If she can't see from that eye she won't see...
I have not used Clavamox as that is obtainable only by vet. Enrofloxacin can be gotten from pigeon suppliers, the oral form. Injectable is vet only. I have used the oral form and the injectable of that. With the injectable there is issue of tissue necrosis at the injection site, so you have...
Does she have any abdominal bloat at all, either fluid or firmness, despite being thin?
For internal laying and EYP the most common antibiotics are Baytril and Clavamox. Amoxicillin might help some but is often not strong enough. So if you want to see if it makes any difference, those would...
Bruising doesn't surprise me. I can't see anything in the pictures that looks concerning.
This thread has some pictures of wounds healing, may help for comparison to what you are seeing:

If she is laying internally, then that is possible, and it's possible she never laid one normally. If that is what is going on, then antibiotics would only be a short term maybe help. As long as that continues, infection will continue to happen. Usually the droppings will not look normal...
The chick also may be straining due to constipation, which can cause prolapse. Take a tsp of coconut oil, freeze it and break into small pieces and feed it all to her. You can repeat daily for a few days, see if that loosens things up and helps.
I think the suggestion of the epsom salt on a...
