I believe that incubation begins about 5 days after the first egg is laid and normally runs about 14 days indigo. So then, we can assume that we should see hatchlings around about 19-20 days after we see the first egg. I have been told that a cold snap coming in will sometimes delay the onset of incubation. Candling the eggs will tell you what you need to know. I think that it is always best to err on the side of extreme caution. Our primary goal is to help the birds to have successful nestings.

Relax she knows what she is doing. Sometimes the female will skip a day and then lay more eggs or maybe she is done. When she is done laying she will start to incubate full time which is not necessarily 24 hrs a day. They know what to do even without our help! LOL Cathy

Leslie, I'm sorry that happened but as many others have replied, we've all made mistakes. Fortunately I had bluebirds nesting for at least two years before a chickadee showed up and claimed another box. Because of this forum, and the helpful members here, I knew that I could protect the dees FROM the bluebirds by adding a hole reducer (to keep the bluebirds out). I've talked to several people over the years (people I know personally and not from this forum) who have removed chickadee, titmouse and brown headed nuthatch nests because they wanted bluebirds. When I listened to their stories I took a deep breath and then explained how much these other species NEED our help. Bluebirds have been getting our help (YEA!) for the last 40 years and sometimes it's easy to forget or not even think about the other species who also need a safe nesting spot. I think that when we put up that first bluebird nest box we only have one thought in mind...... getting bluebirds to nest in our box! I waited FIVE YEARS to get my first bluebird couple! LOL! What I've experienced in hosting three nest boxes is that the Dees and the brown headed nuthatches are just as much fun and such nice little birds! I've never been lucky enough to host titmice but maybe one day.... Anyway, I know you are sorry and won't do it again and that really is the point. Janie

You can move a nestbox with eggs but you have to be very very careful...it is much easier to move a nestbox before the eggs are laid. Conduit is the easiest thing to mount a nestbox on, 3/4" or 1" is the sturdiest. I usually just have a 10ft piece and pound 4 1/2 feet into the ground but 3 feet would be plenty to have in the ground too (some have only 2ft) so you could have it cut. Get a piece of 6 or 8" stovepipe (they come in 2ft lengths) and an end cap for the stovepipe. Drill a hole in the endcap the size of the conduit and place a emt clamp on the pole where the baffle will be (I have mine about 6" or so under the nestbox) set the endcap on the clamp to hold it in place and place the stovepipe around that, attaching it to the cap. Those are from instructions that make it pretty easy...I do mine just a bit differently as I am not up on power tools. ( I clip the top of the stovepipe and fold it over the top of the cap part and use a tin snips to cut the hole in the top/cap. Oh and it should be wobbly...that is what deters the coons the most is the wobble. I then use one hole straps to attach the nestbox to the conduit. Two hole straps aren't as sturdy and won't hold the box as tight as you need it to. Good luck..hopefully you can get things moved quickly before they start laying again. My first year with bluebirds I had them nesting in a nestbox on a wooden post. First nesting went fine..nestlings fledged. Second nesting the nestlings gotten eaten by raccoons when they were 12 days old. I was so sad! After that we put up a properly mounted nestbox and then added more and I also have a small trail at a park now too. Good luck..let us know if you need any more help, especially if you end up moving things when there are eggs. Oh and check out the sparrow spooker page on sialis.org in case you have House Sparrows in the area. Also wren gaurds in case of House wrens...they aren't always needed depending on where you box is located. At my place the boxes on the west side of the house normally need guards as they are closer to the woods, on the east side I never have a wren problem as a road and an open field are there. Donna
