I just want to say to everyone that I truly appreciate all the responses, suggestions and encouragement. I'm having trouble keeping up with all the responses, and want to answer every one if I can. Give me some time; I'll get around to it.
And this..... GOOD NEWS!!!
I made an arm and hand shield from a soda bottle, and my grandson tried it out today with enthusiasm. The grumpy hen pecked him immediately, and you should have seen his face!

"Grandma! It worked! I didn't even feel it!!!"
I showed him to put the basket down so he could use both hands to deal with the hen and move the eggs safely. When his sister came into the coop, he jumped with excitement to show her how the shield worked, and HE explained to her about moving the eggs.
It's her turn tomorrow. And I'll be right beside her. We're going to also try the whisk broom to deflect the hen's pecking, and see if she likes that better.
