What's the N value of this study

I don’t know, but it really should be in units of N dozen.

From the preprint linked above:

> We tested a total of 42 subjects, 17 of which were females.

		The published one repeated the experiment w/ day old chicks and IIRC the same number w/ the same results, so it's got a little more N than the preprint.
