The first eggs were laid in the first week of July, which is the case each year. The eggs take 28 days to hatch and it is then at least 35 days before the chicks are developed enough to fly and there have been problems with predation as in other years.

Both Elk and songbirds have the same basic method of inseminating eggs, which is one of the steps in reproduction (but not by any means the first!), Songbirds grow the offspring internally for only a very short while, and then pop out an egg, which is then cared for over a significant period of time until it hatches.
