Relax, Noodle Girl. The gasp you heard was not because the hen felt it. It is muscles Nothing more, nothing less. Couple of tips. Hold the bird gently upside down for a minute or two. It puts them into a stupor or trance. Also, I use a cone or hang them head down rather than holding them in my lap. Not safe for your lap. The other hen was just ticked that you pulled out her buddy.
I know you love your hens, but you need to get your head around the fact you are doing the best you can do, you are doing what is right and this will be a good dinner! You are learning the hardest part of sustainable, farm living. As soon as you catch the hen, tell her you are thankful for her life. Then immediately tell yourself this bird is no more. It is dinner. I have worked with literally hundreds of kids, always teaching the end result even to kids as young as 6.
You did fine.
