I do not see strong evidence for predator action. If something like a fox tried to worry chickens from outside, then you would be able to see its tracks. Pattern of feather loss is consistent with stress.
Ehh, we've had a fox visit several times and never seen tracks. The ground is pretty hard around there. Although I will say the dog usually sniffs like crazy which he didn't do as much. But I think he did finally pick up the scent of something on the back side of the coop.
As for the feathers, it's not a pattern though. This happened in just a few hours. And they woke up earlier than usual.
They were awake at 4am, well before it's light out, making lots of noise, my dad went out and also shot the BB gun and they calmed down. Then he went back out at maybe 7 or 7:30am and all the feathers were there.
I agree, there really isn't much predator evidence or visible signs of it but there was definitely something wrong. Whether that's a predator or whether they heard/saw something weird, I don't know. But this is not normal behavior for them. They don't wake up until it starts getting light out and they are quiet until one lays an egg at some point in the morning. And they definitely don't lose feathers consistently. The feathers are from every chicken too, it seems. And as I said, they lost all of those feathers in just a few hours. I should have clarified. Those came out at once, there normally are not feathers in the run. I did think maybe one or two was molting but losing them all at once? And there hasnt been any evidence of that or feathers until this
It's definitely very strange.
And considering I had just put her out there for the first time, I think maybe something thought it could have an easy meal? But obviously failed.
Regardless, I have now put that chicken in the garage until I finish breaking her broodiness.
And I do think they're a little bit stressed and the run is a little small so I have been trying to let them free range some every day to get out. But they all are laying, healthy, and have never lost any feathers except when they molted in the fall.
