Thanks! It was touch and go for a bit with these guys. We had that horrible freezing weather starting when they were 8 days old, lasted 3&1/2 days. I was only able to check on them for 2 days before the no peek time came. They were all alive at that time but I suspected a little weak. This batch was not very active so I just had to trust the number of trips to feed and the sound of the peeps. I knew I had at least 3 alive. Most of the time they will fight and push to look out. I have seen as many as 4 at a time trying to sneak a peek but these guys never did. I only saw one at a time. I had expected to find 2 dead babies after the 3rd one fledged as I didn't see anymore peeking, then just as I was about to go open the box, Mom came with worms and there was still peeping! So far I have been through 15,000 meal worms and 1,200 wax worms. I had Dees, Titmice, Nuthatches and a Red Bellied Woodpecker that were all trying to feed their babies through the bad weather. I am hopeful that they all make it (I'm out of worms). If all 5 blues made it the others should be along soon.
Good Luck on your next nesting!
