Incubation is a bust

Our bluebird eggs normally hatch in thirteen days, but not this time.  My expected hatch date on this clutch was 23 July. On 24 July one egg hatched.  I left the others in for three days and Mama continued to attempt to incubate.  Finally I removed the eggs and cracked them.  None were fertilized.  I had a conference with Daddy about his poor job performance and he promised to do better.

Temps are hot, supposed to be 101 degrees today.  The box gets shade all afternoon and is vented, but it still must be like a sauna inside.  The lone chick is getting all the bugs it can eat and is growing like a weed.  I may wet it down with the garden hose this afternoon.  This chick should fledge about 10 August.  It is so well nourished, it could fledge sooner.  I’ve never had a brood of just one chick before.  Hoping all goes well and our lone little one gets out on time or a day or two early.

Total chicks fledged from this box is 101.


Edit.  The lone chick did fledge a day early on 09 August.  We missed it.  I suspect we are done for this year, but one never knows.

    Well at least one hatched. It will be interesting to see if it does fledge sooner with no food competition. I have had one egg not hatch from time to time but 75% infertile seems excessive.
