I have been noticing that my 4 adult chickens will sneak inside and eat the cat biscuits. I decided to do a test, I filled a container with 3/4 layers pellets and the other 1/4 with cat biscuits I chucked them on the ground in front of the chickens and after testing the two they all went for the cat biscuits. When all the cat biscuits were gone they calmed down a bit and ate the pellets. I was just wondering if this is normal and if cat biscuits are bad for them (they don't get much, just when they sneak inside)? And if it is OK for them to eat when I hatch my owns chicks and they are 3-4 weeks old could I soak some cat biscuits in water to soften them and then mash them up?
