I just went outside to give my chickens some left over yellow cake and noticed this mound on my door step. I have 7 chickens, 1 rooster, 2 Pekin ducks and 3 outdoor cats. I am freaking out because I don't know if this is from the cats or from my chickens. All my chickens are acting totally normal, except for 1 hen who is acting normal in every respect, but has been walking around like she's carrying a load, hard to explain it any other way. I posted about her a few weeks ago. She doesn't appear to be egg bound, she's eating, sleeping, acting normal in every other respect, other than her tummy feels a bit firm when I hold her and since I have gotten her, I've never seen her lay an egg. A few times over the past few weeks, I have found a stray egg with a soft shell that has been cracked on the floor of the coop, again, I don't know if this is from her. I also have as I said 3 outdoor cats that bring home birds, chipmunks, voles, baby bunnies, etc. I kept the worms in a small baggie and just looked at them again and they are still moving. Please, can anyone let me know if these are common for chickens/ducks or should I focus my attention on the outdoor cats.
