During a nest check today I found 5 eggs in a compartment with not much of a nest. Thoughts on whether or not the eggs will hatch successfully? Seems like they will roll around and be difficult for the female to incubate. Picture attached.

Probably a SY pair with no nest building experience....I've had a few of those at my colony over the years. I usually help them out and build a nest with a slight depression towards the back of the compartment and the pair typically accepts the help and incubates the eggs. Without helping them out with nest building, the chance of the eggs hatching will be much lower.

Good luck

Agree. It’s a SY pair.. you need to help them out as randy said.. make a bowl shaped nest, with pine needles and some sticks, about 2 inches thick. Put the eggs in the nest.. the martins shouldn’t be spooked.. I’ve done this several times..
Good luck,

Egg orientation?. Probably worthy of a new thread but if you move an egg, aren't you supposed to be careful to maintain the egg orientation?

I don't think egg orientation makes a difference. As a child I remember my dad had an incubator and we rotated the eggs a couple times a day as suggested. Never had an issue with those eggs not hatching. Sometimes I move the martin eggs around with a small pointed dowel to get an accurate count, and it has never affected hatching.

CT, from what I can see you look perfectly normal. It's the other 99.999999 percent of the population I'm concerned about. :lol:

Haha. LOL!!! They do need classes!!

I actually did maintain egg orientation best I could when I made the nest and placed those eggs back inside. I’m a little concerned those eggs rolled around on the flat bottom for a few days and the bumps could have been bad. Also thinking if the SY female tried to incubate some of the eggs but wasn’t consistent…that could also be problematic. Will be a learning experience for me for sure.

Your intervention in securing those eggs from rolling around was the best thing you can do. I've done this for years and have had good success. It is nice to see landlords like you who care enough to make things the best we can for the martins. Thank you.
ImageMite control, heat venting, predator protection and additional feeding during bad weather add up to success.

I guess I was thinking about turtle eggs where apparently orientation is important. Too many critters...no enough brains. :???:
