I normally crush up our egg shells and give 'em back to the chooks or they go in the compost, but this time I thought I'd have a proper look at whether it was a good idea to feed egg shells back to chooks or not. A quick google search later and it seems that it is and that we humans have been feeding shells back to chickens for thousands of years. (Phew - I'm in the majority)
Chooks need a lot of calcium to lay an egg each day and although commercial laying pellets, mash and grain have calcium and all these other vitamins and minerals, I occasionally put my finger through a shell still. So I'm thinking an extra bit of calcium probably wont go astray. I also think that they will ignore it if they don't need it and go in search of what they do need instead.
So armed with four dozen egg shells to make my calcium supplement, Here's what I did...
Green-ness: 5/5 very green to reuse a naturally occurring "waste" product to get new eggs!
Frugal-ness: 5/5 Free is always frugal!
Time cost: About 10 minutes. It took me longer to blog it than to do it!
Skill level: Crushing and mashing skills!
Fun -ness: Good fun to make a useful free chicken supplement!
