@User9609 - Just a rumination about how the adults know which young to feed. Having worked with young children, you know pretty soon in the morning which ones have had breakfast and which ones haven't. I've no idea about swallow's sense of smell but a simple feed (or take sac from) the smelliest one first and, if it all smells hungry, feed the loudest (i.e. the liveliest) first strategy could work quite simply.
