29 April 2012

Yesterday, Saturday, April 28th, marked the beginning of the 5th week since the first egg was laid. Incubation is anywhere from 5 to 6 weeks so the first chick could hatch any time now.

In the last few weeks, Jasper has been bringing in quite a few large bass. If that trend continues, we shouldn't see the chicks go hungry. If the chicks don't receive enough food,  aggression between the chicks will intensify and can be hard to watch. That is a completely natural, wide-spread and adaptive behavior.  Chicks hatch over a span of many days, and so there can be a large difference in size among the siblings in the same nest.  This is called “hatching asynchrony.” They are covered in down when hatched. 

Bea is constantly up and down over the eggs as of this post so the first egg could possible hatch today. The first chick hatched on the 40th day in 2011 and in 2009 it was the 38th day.
