So I just put my girls out in their new run and leave them out all day and then bring them in at night. I had issues getting them in so I've been leaving them out all night (with shelter to sleep in until our coop is done). I check on them every morning before I leave for work and as soon as I get home. Yesterday, I got home from work and saw some feathers on the ground as I walked up. Then I noticed more and more. All the girls came out to greet me, and as I counted, I found that 3 were gone. There was MAYBE a large handful of feathers in one area and very VERY little blood. I had to really search to find the blood. The run is pretty secure and I have no idea how something got in AND out with 3, 7-8 week old chickens. I'm mad and sad all at the same time after spending so much time and energy on them for 3 to just disappear. I mean there is NO sign of them or which way it would have taken them. I want to say it was a cat that got them, but I'm not certain. Anyone have this happen before?? Just seems so strange because it was just some feathers laying around and no sign of a lot of blood. Needless to say, I've brought the girls in for now until I find the source of my issue and will "take care" of it.
