I tested eggs pre incubation using the pendulum method. I attached a large needle to string, held an egg in one hand and the pendulum above it. The needle will start to move on its own. Ive read conflicting statements about which way for which gender but after testing it on all the people and dogs in my house, decided to read side to side for female and front to back for male. I set only the eggs that tested female. During incubation, they always tested the same. They continue to test the same after hatch and two weeks later. At two weeks old I can't say for certain but all 9 of my hatchlings look female to me with how quickly they feathered in. Guess I'll know for sure in a couple months but I'm nearly convinced this is the most accurate way to end up with few to no roosters. Would love to hear if you've tested this. I think most people are too suspicious to even try 🤣

I'll be really curious to see the results when they are old enough to be sure of sexes!

I haven't tested it, but I have definitely thought about it. If I ever do get around to testing it, I'll probably put "female" eggs in one incubator and "male" eggs in another, then keep the chicks separate until they're old enough to sex for sure. Hatching all the eggs will give me a check in case the sex ratio of the whole batch was skewed for some reason (I once had a hatch of 11 chicks that had 9 males and 2 females. If I had tried to do a sex-in-eggs experiment with that batch, it could have really screwed up the results!)
 
The user unconsciously influences the movement to what they hope or what they know, there's not any science behind it. I've only had one male feather in slow and I've had chickens for over 20 years, so feathering in rates aren't a set in stone way to guess gender.

Good idea! I was too afraid to have any more roosters to deal with lol. The breeder I bought from in the spring is going to let me test it on his next spring hatch so I'll have a larger sample.

I'm open to having had that bias after the initial test and on the creatures in my house that I already know the gender of. However it was really interesting to me how the first test went down, it definitely responded specifically for each egg. If its successful, I would argue that my unconscious influence should probably be trusted/ wonder if the intuition of the user is a variable. Stranger things imo but I do have a healthy scepticism. I'll post back with updates
 
Some of my family have been doing this on everything for like forever. Needle on thread and wedding rings on a chain.
They've always done it if it swings back and forth it's a male. If it swings in a circular motion female.
Yes it works... about half the time.
