Never raise chickens next to a potato patch. The smell of the potato plants will make hens quit laying eggs and start setting.
If you collect eggs and put them in a woman's bonnet to transfer them to be hatched, they will mostly hatch out pullets (hens). But, if you put the eggs in a man's hat, they will mostly hatch out to be roosters.
Any eggs that are elongated or sort of 'rough' on one end, are thought to be 'rooster' eggs and should be avoided putting in a clutch to hatch.
A sure trick to protect your chickens from varmits is to pull one feather from each chicken in the flock and bury the feathers deep in the dirt under the hen house. As long as they stay buried, the chickens will remain safe.
And most important~never give away a chick or you may be giving away your 'luck' with it. Any payment will prevent this curse, even just a trade of something, like a bucket of berries or garden produce for the chicks.
I've been trying to remember if we've given away any chicks, LOL!
