After a day of having nothing else my hens have taken to their crumble well, but my rooster is not interested. Sometimes he'll take some when the hens are eating it, but mostly I have to hold a handful of it in front of him to get him to eat any. Is there anything I could mix into the crumble to entice him to eat more, or would that be defeating the purpose? I'm pretty sure nothing's wrong with him. He looks and acts very healthy. I wanted to cut scratch because of it's low nutritional value, but now I'm worried about his caloric intake. I know he's not eating as much of it of his own volition as the hens since I've compared the sizes of their crops when I lock up my coop at night.
