I had two hens and one rooster. Now I only have one hen, the rooster was laying in the chicken pen dying, I cant tell how. The other hen was gone. I walked around the pen...nothing, no evidence of something digging or the fence wasnt messed up. I found a few feathers...but thats it. The other hen was just walking around, I could tell she was freaked out. the pen is fully coverd, so I dont think anything flew in there. I am new to raising chickens and this isnt the first time ive lost chickens but I thought I got rid of the problems. Its like one after another! I want to raise chickens badly, I enjoy them soo much but its like everytime I start getting attached, something happens! Anyways, anyone think it could be a snake? I have four cats, two are kittens. but I dont think they would do anything, they are lazy and well fed. But im thinking either cat or snake....Any advice will be appreciated.
