I was wondering if I should clean out the food that's been billed out or spilled (which is a lot), or can I just leave it so they can eat it when they scratch. My chicks are 3 weeks old and I keep the brooder pretty clean. I know that fecal matter would be a concern, however they manage to get feces in their food container as it is. I would appreciate any thoughts, opinions, advice, etc. Thank you!
