Update on Shelly...she's doing great (see first photo), and in fact did turn out to be a she. The second photo shows two nice little pullets and a nice cockerel spending time with some New Hampshires. All of these Penedesencas hatched on or around November 19, 2015, from eggs I got from Guy/ChickenCanoe. They're doing wonderfully well. I found it really easy to sex them early, given the cockerels' nice, dominant combs, which appeared when they were quite young. At seven weeks, one of the little Penes has already started to crow.
