Describe the pen that vandals and the other woman built for their tykes.

From the text:

It had been only a few days, but the women had gathered thorn bushes and circled them around the remains of the cott where Kira had grown up. The encircled ground was still ashes and rubble. Very soon the thorned fence they were building would enclose the area completely; she supposed they would create some kind of gate, and then they would shove their chickens and their tykes inside. There would be sharp wood pieces and jagged fragments of broken pots. Kira sighed, seeing it. The tykes would be scratched and splintered by scraps of her own destroyed past, but there was nothing she could do. She edged quickly past the wreckage and the half-built fence, and found the remains of her mother’s color garden at the edge of the woods.
