Kara, also at the nests, sniffs. "Well, we have another problem. Someone or something's already farmin' the birds. See those rocks? Someone put those there and took one nest's worth of eggs in exchange." She gives the incubator-volunteer a sidelong look. "If you like. I won't lie, I'd like to eat one of those eggs; dunno how many we'll be able to raise. Did you kill the females, or just the males? But whatever we do, we should keep sniffing around here. I don't know if animals are smart enough to substitute in rocks."
