I have 6 of 21weeks old SS. I feed them 2xday with mid container full. You know that mid-size container when you buy salad from super market deli. Normally when I put in the food in the morning, it will be gone by end of the day then I will add one more container full. But getting cold here so I started feeding them chicken scratch. I do a half of same container 2xday. Now regular food is left a lot. Seems like they only eat a half of amount they used to. Is that mean, I'm feeding too much of chicken scratch???
