Many are concerned that Tom is negligent in bring home the "bacon".
I think, from what I have read from the posts, the feedings, at the beginning, were not coming enough because Audrey and Tom were treating them as newly hatched chicks, not older ones that required more food/feedings.
Also, from what I've been watching, they have had some bad weather, rough waters, high winds etc., which makes it very difficult for the male to hunt for fish.
But, I think Tom has done a pretty great job thus far to keep his family fed.
They are growing quickly, and that nest needs some work around the edges.
I think it's a successful fostering, so, I wish them well.
Happy watching!
