LOL Science experiments are always good with the hubby! I agree, I like your reasoning too!

I wondered if my breathing moved the needle so when i tested i turned my head away. LOL, had oldest son look and tell me. If it's accurate and he understood what to look for, I have five hens out of seven chicks.

I have decided how I can find out if it is true. I am going to just collect eggs from some of my sex links. You can tell them apart when they hatch so going to only put in eggs that say pullet and see if they are all pullets. That way if it works will have my egg layers for spring and no roos to get rid of. Will post results when I get enough eggs together to test pullet.

I think this sounds like a great way to test it. I can't wait to hear your results!

I am now going to back and read all of thread....but......that is how I tell. It is pretty accurate. Cool thing is that if you don't need roos you can do it with the eggs and not put the male eggs in bator.

I have a better rate with eggs than chicks because of this. By the time I see the chick I have already sub-consciously thought it/they look more like roos or hens or what ever. Then the accuracy goes way way down.

I tried this on some Delaware eggs before I put them in the bator. When I tested them, the pendulum did not move at all over any of the eggs. I guessed this is because none of the eggs contain any live embryos yet, so sex determination hasn't even begun within the egg itself. Is this logical? Seems logical to me. I'll be candling the eggs on Tuesday night, and I'm going to do the pendulum test on them probably Wednesday night. Can't wait!

Why not number the eggs and do it at the same time you candle them. It shouldn't take that much longer. Good luck!

The chicks were 7 weeks old yesterday. All 14 packing peanuts are definitely boys. With the 10 bantam cochins, the original test was correct in the number of males and females - there are 5 of each.

But now I am having a hard time matching 7wk old chicks to their day-old pictures to see who was who. There are 4 who I can definitely tell who is who, and two of those the pendulum sexed right. The other two are a male and a female, and the pendulum got them wrong.

So out of 10 straight-run bantam chicks, the pendulum was wrong on at least 2.

This is not a fool-proof method!
