One of our chicks is having a tough time transitioning from eating off the ground in the brooder to eating out of the red plastic feeder. She's just not interested. I have overfilled the feeder to where the food is practically spilling out the little holes. What else can I do to get her to use it? She's already kind of runty (at nine days old), so I don't want her missing meals. I feel like I'm going to have to break down and put a tupperware lid with some food on it for her in there. Help!
