This is BirdNote.
Birds鈥� eggs are among nature鈥檚 most elegant creations. But they鈥檙e not easy to make.
This American Robin will lay one egg per day for three to four days.
To make her eggs, the female robin has to use a great deal of calcium. But she can鈥檛 just pour herself a nice big glass of milk. She has to find her calcium in nature. And it can be tough to find enough.
But we can help. During the nesting season, we can give the birds that visit our homes some of that crucial calcium.
Start off by putting calcium-enriched seed and suet in your bird feeders.
For the many species that don鈥檛 eat seed or suet鈥攍ike robins鈥攜ou can give them leftover chicken eggshells instead.
Rinse the shells off in the sink, spread them out on a cookie sheet, and bake them in the oven at about 250 degrees for 10 minutes. You just want the shells to dry, not brown. When you鈥檙e done, crush them up.
Crushed eggshells can be mixed with birdseed and set out in a feeding tray or scattered right on the open ground.
And remember, always wash your hands after handling raw eggs.
