Egg shells for Martins

Postby Spiderman » Sat Jun 02, 2018 1:28 pm

I have never put out left over egg shells from the kitchen before this year. Tried the crushed oyster shells, even crushed them finer into almost sand but no takers.

But the chicken egg shells are a different story. Had a bare spot in the yard with just dirt. Broke the shells into small pieces, put out 6 egg shells. There are 10 or 12 Martins at a time feeding on them as l'm walking away.

If you have the time you should give it a try.

WOW ! That’s pretty cool. I had considered when I get some established birds installing a raised platform next to my gourds for eggshells,say maybe 8-10 ft high.

The females will chow them before egg laying. Also they feed them to the babies as their bones develop. They love the eggshells! Good luck! :)

I've tried platforms to get my PMs off the ground (I worry about hawks), but they won't touch them, but crunch the eggshells up very finely on the concrete driveway with my feet after the eggs are well sun baked and dried and the PMs flock to them, along with the Barn Swallows and Tree Swallows. Maybe it's the grit, maybe it's the calcium, but whatever it is they want them.

Ours are eating 6 egg shells a day. I started mixing the whites from the boiled eggs and they ate them too.

They wouldn't go for the scrambled eggs. Not sure what the difference was with that.

Eggshells might be one of my biggest PM successes as a second-year landlord, i.e., they devour them, and yes, they do in fact feed them to their babies; I've watched them with binoculars, and my egg shells are really disappearing now that several pairs have babies.

They still prefer them crunched into fine pieces on the nearby concrete driveway, and will not go to the elevated feeder. The Barn Swallows join in as well, especially in late afternoons.

Mine love the egg shells taken off my bed & breakfast platform, and I am hoping it will help to train them to take supplemental feeding as well. So far I have had no luck with supplemental feeding, but they readily take the egg shells.

I must be lucky because mine always take the oyster shells. They are cheap and I have a raised try. Fill it up before egg laying and they use it all season.
2018- Currently 14 pair nesting, 35 babies hatched and 15 eggs (6-22)
2017 3 SY pair nested, 12 eggs total, fledged 10. 4 additional SY's stayed all summer but never paired/nested.
2016 1 pair fledged 4

Parent martins will take crushed small egg shell pieces back to the cavity for their young. Calcium in the egg shells help build strong martin egg shells as well as replenish the females own calcium in their bones. It is also an excellent source of grit for martins.
Mite control, heat venting, predator protection and additional feeding during bad weather add up to success.
