Got eggs of these last May. After having the Silky-sized Peruvian Araucanas - these looked HUGE! The roosters eyeball me, asking for treats, as I sit on the Adirondack-chair in the yard - their heads are above the armrest! I have to guard my food! Mine are not aggressive. They don't like being picked up, but they don't run away, either. They come hang with me when I sit in the pasture. Kinda slow growing, but they put on enough bone to hold them up - unlike Rock x Cornish. Anticipating when they start laying eggs - the hatching eggs were fist-sized! Ate two extra roos already - nice meat! Got these to start a meat-flock while my Araucanas work as layers.
