I see the female caught six fish yesterday and the male one so everyone should be eating well. Apparently baby Huey did win a food tussle with the little guy at one point.
I know you're not supposed to interfere but I don't see how the citizen scientists(volunteers? lol) can just stand by. I'd be tempted to give the big doofus a flick in the ear while taking his food away and giving it to the little one.
