I had been wanting to keep a photographic record of how Silkie chicks grow up, so when I had two hatch I took a picture on hatch day and at one week intervals after that. As it turned out, the two chicks were male and female. Here is a slide show of their progression. The female is the chick with the more vaulted skull.
