Oh no, I totally agree with you! I have cats and have never had an issue with them and in the predators section when people are concerned about cats, I'm usually the first person to tell them they don't need to be. However in my experience, cats switch from being predatory towards the chicks, to being afraid of the grown birds, around the time they are fully feathered. Since these were silkies and don't have the feathering of most chickens - and being bantams are much smaller that the LF you and I keep too - I considered a cat an option, mostly because whatever did this is something that got into a yard protected by a 6' fence and got back out again without being seen. If it were a dog, I would think it might have got into the yard but would have still been stuck in the yard when Cailynne made the discovery. If it went under the fence, there would be an obvious place where it dug under, so that only leaves going over, and, assuming it is a wood privacy fence, those are easier for a dog to climb and go over in one direction than the other, where a cat wouldn't have any trouble going over it from either direction.I also looked at the pics, but couldn't tell anything from them either. I know cats get blamed for a lot of things, but HEChicken you saw how many we have here & in all the years I have had chickens, both here & at my other house I have never had a loss from a cat. My grown chickens put the kittens in their place by pecking them on the head, so I can't imagine them getting the better of a grown hen. The only ones my cats even show any interest in is the chicks & that is just I think because they still peep & that causes them to pay attention. They have not tried to get in the pen however, they will look in there, but mostly they just want their food. The kittens will get into my FF when I'm trying to feed all the chickens in the evening, they obviously like it too.
