At 8:40 this morning, the Loon Cam 2 female laid the second egg, about 61 hours after the first egg. That’s a longer than average time span between eggs and, considering that the first egg was getting almost constant incubation for the last 36 hours or so, the first chick to hatch should have a significant developmental advantage over the second chick.
You may recall that last year this pair’s dominant chick severely persecuted it’s younger sibling, eventually resulting in the second chick’s death. Will we have a rerun of last year’s outcome? That will likely be a major topic of conversation on the YouTube chat. But keep in mind that it’s more than just the age difference between chicks that that governs sibling rivalry. Individual personalities are also a factor. We won’t know exactly how these chicks will behave until they hatch.
