Athena looks very content this morning with the new chick under her breast. Waiting to hear about the first chick and eggs.
From Nestbox News May 17, 2013, 2:40 p.m. - Mission Accomplished! Biologist Mick Valent, along with Mackenzie Hall of the Conserve Wildlife Foundation of NJ, successfully removed the ailing chick and infertile eggs and placed the Sea Isle City chick in the nestbox. Moments ago an adult entered the box (see photo to right) and briefly brooded the chick. This behavior is what we had hoped to see - a quick "adoption" of the new chick, though it is impossible to tell just what the Jersey City peregrines perceive or "think" about the past half hour.
The chick is now en route to The Raptor Trust for examination and care. We'll update this page later tonight or tomorrow morning, but viewers will know about as much as we do for now.

Bad news, good news. Here is the post from NJ Fish and Wildlife. The end result was that they made the switch and Athena and Six accepted the new eyas immediately. We are awaiting info from Raptor Trust and dr. Erica Miller.
May 17, 2013, 8:00 a.m. - A Plan Is Formulated We have been carefully watching the chick that hatched on Tuesday morning, and we've concluded that the hatchling is not well. It seems to suffer some of the same symptoms we saw in the third of three chicks hatched in 2011. That young one also failed to thrive and, despite heroic treatment that lasted for months, he eventually died. It seems that this nest is having more than its share of problems.
In the nest on Thursday, the chick was not sitting up, which is necessary for it to be fed. It had gotten fed each day, but on Thursday the chick seemed worse, spending most of its time lying down and even apparently stuck on its back. This is not normal for a chick that is two days old. The other three eggs have not hatched and we don't expect them to hatch at this point. The adults are still trying to incubate them, which is also distracting them from the chick.
We may be seeing the lower nest success that is characteristic of older peregrine falcons. While our female remains an excellent caregiver, her eggs have lower viability, and the chick may suffer from a genetic abnormality. The eggs could also be carrying accumulated toxins that are interfering with hatching and normal chick development.
In the interest of keeping this pair active at the nest site, we will be providing them with a foster chick this afternoon that we're transferring from a four-chick nest in Sea Isle City. Biologist Mick Valent will put the chick in and remove the eggs and the sick hatchling. He will deliver the hatchling to The Raptor Trust, where we hope to get a clue as to what is wrong. The eggs will be valuable samples for future analysis.
Fostering chicks into nests is a proven technique and we fully expect the Jersey City adults will quickly adopt the new nestling. By doing this, we will allow the birds to fulfill their nesting cycle, giving full attention to raising one chick. The donor nest also benefits, because the adults will have a little less work raising their three remaining chicks. At both sites, we raise the chances of ultimate survival for all the young.
