Black Jersey Giants

M and I were walking the East River Trail this afternoon and stopped to check on the chickens.  There is a new flock of fluffy, glossy black hens that are being kept in a fenced off area under a small tree.

I googled them when I got home and determined that these are probably Black Jersey Giants.  The curious thing about them is that they were sitting in a pile-up under the tree.  Every now and then one or two would venture out into the grass and peck a few times;  then they would scuttle back to the heap.  I've never seen hens pile up like this before!
