Did you know that our feathered friends need calcium in their diet, too? And that you can provide it for them with very little effort?"A dry chicken eggshell is about 78-94% calcium carbonate (CaCO3). Calcium carbonate gives shells hardness and strength."
You can supplement calcium by offering dry, sterilized, crumbled chicken eggshells (or crushed oyster shells which can be found at your local feed store) mixed in with mealworms, birdseed, suet, or simply spread on the ground, a rock, a platform feeder. As a matter of fact, if you are supplying mealworms, your birds will need a calcium supplement because mealworms deplete calcium!
Spring is an essential time of year to begin offering eggshells as an assist to breeding females to ensure strong and healthy eggshells. Throughout the summer, providing eggshells benefits both young and adult birds. "Calcium deficiency can cause developmental problems in growing birds. Lack of calcium can cause weak bones in adults."

I remember long ago we fed oyster shell to the chickens!
ReplyDeleteKaren: How nice to share this with us less experienced feeders.
ReplyDeleteGreat information for nature notes.
ReplyDeleteNO WAY! This is such a simple idea. I like learning things like this and I'll try it out.
ReplyDeleteHey Karen! I love coming here and learning so much, thanks for spreading your knowledge - the birdies thank you too! I'm going to try this tomorrow. I'm assuming that eggshells can be sterized by boiling? we love hard-boiled eggs so that'll be a cinch. I'll check out your link too. Also have a quick favor. Can you check out my friend Marlene's post, link below, about a moth (I think it's a moth) she photographed? I told her I'd contact you - thanks!

Thanks for sharing the great tip. Have a wonderful day :)
ReplyDeleteThank you for that... I never knew. So easy to do as well!
ReplyDeleteThis is very interesting. I wonder if that has anything to do with the male bluebird that has a short tail. This year a male has claimed our birdhouse and his tail is much shorter than I have seen on bluebirds before. I know they eat mealworms even though I don't provide them.
ReplyDeleteGreat info on the much needed calcium for the birds. I have heard about offering eggshells to the birds.
ReplyDeleteI've heard of this but haven't been doing it. Thanks for the reminder, Karen! I learn something in every one of your posts.

Hi karen,
ReplyDeleteThank you for posting this excellent piece. My family used to offer crushed egg shells to the birds, I thought they were mad, until I read up on it.

I've heard of feeding egg shells to the birds, but not done it myself. I didn't know that fact about mealworms, either. Thanks for a very informative note.
ReplyDeleteThis is such important information and something i need to do...michelle
ReplyDeleteThat is sooo interesting! It never occurred to me to offer the birds calcium!

ReplyDeleteGreat information. I'm going to book mark this post.
ReplyDeleteBut feeding chickens egg shells might result in them starting to eat the eggs too. Mightn't it?
ReplyDeleteYou always have so many interesting tips on your blog! We have a lot of birds around our place (mainly eating the olives off the tree!)
ReplyDeleteGreat tips, thanks for sharing with us!
