Well, I think you have unveiled the mystery of how to make these hens:)
You will need a kitchen glove. Blow it halfway. There must be enough glove remaining, that will be used for a nest. Tie the glove well with a rubber band.
Cut soft paper into small pieces and put them into that part of the glove that was inverted inside out. When you are ready, on top of it put green paper grass (see how it is made).
And finally – the funniest part – the decoration of the hen. You can use markers, feathers and all kinds of coloured paper.
