Hello- I have breeding flocks of both Partridge & Wheaten Penedesencas. They are elegant birds with beautiful lines, nifty looking blue shanks, and jaw dropping, stunningly dark eggs. Mine are in a LARGE pastured run, but are kept in a smaller run when breeding with no change in their temperament. They forage very efficiently. Penedesencas aren't my friendliest chickens, but do tame down well if you take the time to handle them around their bedtime. Handling as chicks seems to have little influence. My roosters are very gallant to the ladies, and again, while not my "best buddies" are companionable and eat from my hands. My girls have been reliable layers and are always curious about what I am up to. One rooster did suffer some frostbite from our last winter on his comb (we had two weeks of day hovering from around 12-18 degrees F), but none of the hens had problems. I feel these birds are worth keeping and breeding. They also produce really handsome hybrids when bred with other dark layers like Welsummers or Marans. The Maran hybrids are autosexing. So far I have only crossed a Wheaten Pene rooster with Welsummer & Cuckoo Marans hens. Their offspring maintain the plumage of a Welsummer for the former, the plumage of a Black Copper (?) for the latter, and the shape/size of a Penedesence with over 80% having blue shanks. These have been good layers with lighter eggs, though often heavily speckled.
We sell Fayoumi chicks yearly where I work. They are some of the loveliest chicks I have ever seen, with russet coloured heads and dusky speckles over their backs. I have yet to raise any as I don't care for their adult appearance and prefer breeds that are less feral. Even as chicks they seem rather wild natured.
I have no experience with Empordanesas.......
