Mornin' all
Loving the discussion on how to hatch pullets vs. cockrels, lol

What I would LOVE to do would be to do a big experiment with something like 3 sportsman incubators one on normal temps, one on cooler temps, and one on the hotter temps, run each one with a batch of eggs from three different auto sexing breeds (that you could sex at hatch), and do it once a month for a whole year (to prove or disprove the time-of-year theory) and I'd LOVE to see the data off of an experiment like that

Maybe even from three different breeders doing this experiment in three different areas of the country (or more) However, I can't IMAGINE what you would DO with ALL THOSE CHICKS, lol!!!!! (ESPECIALLY if you ended up with some all cockerel hatches
I HAVE had limited success with the ACV in the water with my easter eggers a couple of years ago, or at least appeared too. I had been hatching at about 2/3 to 3/4 cockerels for a couple of batches, then found out about the vinegar and tried it (also was experimenting with wing feather sexing) and it APPEARED to lower it to 1/2 to 1/3 males, however the last batch ran into cocci and a majority didn't survive (very frustrating) The ones that did I ended up with 1/3 males. So I bought a gallon of the braggs ACV and ran off a BIG BATCH of eggs and towards the end of the incubation the incubator blew and ran 105 temps one hot summer day before anyone caught it and it cooked everything
And the incubator is still not fixed, (although told hubby that's what I wanted for Xmas, lol

) So my theory stands for more testing very soon
I also read an article on chick sexing methods in maybe backyard chicken magazine website? (a few months ago) and it was talking about the egg shape sexing method, how it works some of the time. Since hens determine the sex of the egg, and each hen typically lays a similar sized egg, some hens throw a majority of one sex or the other. So if you have a hen that lays either a long or a round egg and she consistently throws more of one sex or another it would
work for her only since every egg she laid that was "long" would be a cockerel (or a pullet depending on what that hen always threw)Now for me that makes a lot of sense since I have a beautiful buff and white easter egger than I've wanted more hens like her ever since I got her. Well, every chick that I've hatched that survived that had her coloring ended up being cockerels, so I think that theory might be correct.
Also, two years ago when the incubator blew, that year we had a beautiful pair of millie fleur cochin bantam project birds. Was planning on getting into them in a big way. We hatched EVERY egg they laid, and had probably a 50% hatch rate. But for some reason EVERY CHICK THEY HATCHED WAS A PULLET. I've been with my hubby for 12 years and we've raised cochin banties for almost all those years and I have NEVER seen anything like it, nor had he, and he's raised them since he was 11! However, every one of them grew normally for 6 weeks or so to CUTE little fluff balls of feathers, and then quit growing all together and then eventually died at three or four months of age at the same size they were at 6-8 weeks. Then the hen died this year so can't test that any more.... So maybe you jsut have to find that magic hen/rooster combo who will lay the same sex all the time.
But anyways, just some thoughts running through my head this morning
SOOOOO going to start pulling my Marans hens out one at a time and hauling them down to the chicken house's cages (set up for a trio or quad of banties, but will work for maybe one or two marans later when I start hatching) and leaving them there until they give me ONE egg so I know who is laying what eggs and banding them that way so I can nail down which hens I'm gonna breed to which roosters, and which ones eggs are so light I won't breed at all. Now who wants to hazard a guess they'll go on strike and won't lay until they're back free ranging again
I've got one larger sized cage open right now so I figure I'll haul them down one at a time instead of taking them all down there at once.
OK, I'm off here this morning, got to go and get stuff done
