Why would later eggs mature faster without the same warmth that the early eggs aren't getting either?<BR/><BR/>Interesting.<BR/><BR/>I'm told with Red-tails that the formel will only sit half down until the clutch is completed. Thereby keeping the first eggs laid at a slower growth rate. Then she sits full down when the clutch is complete. At that point the eggs all grow presumably at a similar rate.Donegal Brownehttps://www.blogger.com/profile/09809720759418462703noreply@blogger.comtag:blogger.com,1999:blog-27276563.post-8141960496037067732008-04-01T02:46:00.000-04:002008-04-01T02:46:00.000-04:00The derby peregrine falcons are leaving their eggs...The derby peregrine falcons are leaving their eggs uncovered for considerably longer than that. The wildlife folks there say that is normal, to give the later eggs time to catch up. Does this vary by type of bird?Anonymousnoreply@blogger.com
