INDIANA BYC'ers HERE!

hot water freezes faster than cold water.
There are some specialized cases where this can be made to happen. Mostly, it happens because of variables that are hard to control. If the hot water is near boiling, a lot of water evaporates from the hot container, thus there is less water to freeze. If a hot container and a cool container are placed on ice, the ice melts to form a more perfect contact with the hot container, increasing the heat transfer on the hot container.

When all things are equal, the hot water loses it's heat for a period of time until both containers are the same temperature. At that point, they will lose heat at exactly the same rate, until they freeze. The hot container doesn't somehow remember that it used to be hotter and lose it's heat faster than it normally would.

Given that the hot water will take some time to reach the same temperature as the cold sample, that time is lost.

This phenomenon has been argued and tested over since Aristotle's time.

From what I have gathered, experiments can be set up that will seem to verify it, but there is always a "yeah, but" moment attached.

Try it this winter. Set several matching glasses with the exact same amount of water in them with varying temperatures cold, lukewarm, warm, hot, near boiling on your porch this winter and set a timer to remind you to check it once every 5 minutes. See which ones skim over first. Weigh them to ensure each glass is the same and the amount of water before AND after the experiment is the same. You will then be the definitive expert on the subject and you can either bow to my superior knowledge or demand my subservience to your most magnificent being, the keeper of all knowledge of importance.

Awww, how cute. that sucks that none of the shipped egg ceveloped.If you dont mind me asking, Who did you buy from?

I can tell you that they have excellent results when the ship normally. However, most folks are hatching them in an incubator. When eggs are shipped they get jostled. There's no avoiding that.

If you're using an incubator you can set them upright in a carton while they are developing and just tilt some to rotate rather than having them lying on their side like they are with a broody. It's my opinion that they have a much better chance of developing to hatch in that kind of scenario WHEN SHIPPED.

Of course, the 3 that hatched weren't shipped or jostled. Just put from the nest box to the broody.

So...I think if I purchase eggs in the future I'll wait till I have a broody, incubate in the incubator, then place the chicks under her after hatch so she can mother them. That will be my next experiment with shipped eggs.
 
Have to get an incubator first since I don't own one!

I buy a lot of hatching eggs. I have never hatched in egg cartons. I lay them on their sides and flip them twice a day.

so this lil guy happened today. My silkie has only been sitting on these two leftover eggs in the evenings/over nights since her chicks were born last week but I didn't have the heart to pull them yet. I really didn't think they'd make it. This morning at about 7am I saw that one had pipped. Hurray! When I got home from work today I expected a new little fluffy, but the egg was unchanged and of course mom and babies off the nest. I made a tiny hole with my finger nail (it hadn't made it thru the membrane) and I could see it breath and move around. I was worried it would dry out since mother of the year was ignoring it so I put a couple drops of water around the pip. In an hour voila! Baby! Momma hen ignored its pleas though so I put it under a lamp to dry off. Just put it back under momma this evening. I hope she accepts it!!

I have some cups in the freezer right now. cold,warm,and hot. I did this experiment before, but want to make sure i get all the details right. I put 1/2 cup of water in 3 identical cups. I will let you know the outcome.
 
Well...maybe my theory is not good...
hmm.png


I know I let them set in an egg carton to hopefully reattach the air cell for 2.5 days before placing.
not saying your isnt good, alot of people hatch that, way I just havent every tried it. I'm not willingto risk shipped eggs that I spent a lot of money on. I am going to try it this summer with some of my own eggs, that way i dont lose any money! I only let mine set 20hrs. Most websites say 18 hrs. Everyone has their own methods.
