I apologize for long post but in April I watched mom chickadee build nest on nest box camera. Layed 1st egg April 14. All together she layed 9. Only 2 eggs hatched a day apart. The 2nd baby was MUCH smaller and disappeared about 4 days after hatching. The 1st baby continued to do well. Slowly 1 by 1 the remaining unhatched eggs started disapearing. Baby still doing well starting to flutter wings at 13 days old. At this point only 2 out of the 7 unhatched eggs are visible on camera. The next day no unhatched eggs are visible. A day later I came home and nest was totally empty so I thought baby finally left all is well. To my surprise mom came back to sleep in nest that night (last night) but this morning when she left there were 3 eggs! She returned several times today and as I type she is sleeping in nest box again! Im confused. What happened to baby. Is this the same mom? Were did 3 eggs come from in one day? Could these be the unhatched eggs that she hid and still trying to incubate them? I assume its same mom because she can careless about sparrow spooker. Could she have saved these eggs. I feel so bad for her if she is trying to get them to hatch because I assume they are dead but she is even rolling them around. Also I assume she could not of layed 3 new eggs in 24 hours. Any thoughts on what is going on?
