Very good surprise and very very cute!!! I'd mark that hen for later breeding and brooding.
Been having my very first dedicated predator here of late and thus far it has gotten more chickens in two weeks than I have lost altogether in the past 40 yrs of free ranging. Haven't even seen it but am pretty sure it's a Great Horned Owl....got one right in the coop and attacked a few right next to the coop, despite the dogs being on guard and that takes some doing...of the two injured, I culled one and the other died before I could cull her...all signs under the skin showed razor sharp talons were in use. For now the flock are getting locked up in the coop after evening feeding and not let out until full sunrise in the morning....we'll see what transpires after that.
Oh Bee, I am right there with you!! The one hawk attack we had took place under complete bush cover; right next to coop, with everyone milling around in shock. Two bantam roos that time. I wonder if we're in for a doozy of a winter.
