I was just going to post asking a protein question so I thought I just add to this. Sorry, you can move it if I goofed.
The protein of our Agway is 16% for pellets. My old girls really went through (and two still are) a very bad molt and read here about boosting protein (and possibly dissuading picking) by adding dry cat food. They love it, and although they are eating their layer pellets well, they are going through ~ a cup of cat food a day too. They also get grit, oyster shell and anything else healthy and they eat it all. Is this too much cat food for 9 hens, 5 of which are bantams?
