Set the Rails Before You Set the Eggs

Set the Rails Before You Set the Eggs

Christian here. Labor Day is Monday, September 7. From Bridgewater, that is the last easy stretch of late summer — still warm days, cooler nights starting to show up, and a holiday weekend when carriers get sloppy and everyone suddenly remembers they wanted birds before winter.

We ship within 2–5 business days (or on a date you leave in the cart notes). If you want rails and eggs on your counter before that long weekend, order them this week. Friday night is how you end up setting a machine in the second week of September and wondering why the schedule feels late.

Coturnix are on a short clock. They hatch in 17 to 18 days. That is not a guess I am making up for this post — it is the same timeline we already walk through on the CT180 write-up. Set this week, hatch around mid-September, and you still have a reasonable window to brood before you are fighting the first real cold snap.

The part most people skip

People obsess over the cabinet. Temperature, humidity, lockdown. Fine. Then they drop jumbo Coturnix eggs into a standard Conturn rack that was sized for chicken eggs and act surprised when the eggs roll, wedge, or sit on their side for two weeks.

I will be blunt: if you already own a Cimuka / Hatching Time CT-series machine, buying a second incubator is usually the wrong next dollar. The rack is the problem. The rails are the fix.

We make two drop-in rail families for those Conturn turners. No tools. You do not modify the incubator. You do not mix egg sizes in the same pocket and hope.

  • Jumbo Coturnix (about 14–18 g): deeper, wider pockets. That is the Jumbo Quail Egg Rails for the CT60 — a full set of 12 rails, $59.99, enough to outfit one CT60. CT120 takes the 24-rail set. CT180 takes 36. Same idea, more pockets.

  • Button, smaller Standard Coturnix, Bobwhite (about 8–11 g): standard Conturn pockets are too large. Eggs micro-roll and drift point-up. That is the Standard & Button Quail Egg Rails for the CT60 — also a 12-rail full set at $59.99, with 24- and 36-rail sets for the bigger cabinets.

They are rigid, smooth, non-porous polymer. Wash them between hatches. That is the whole pitch. I am not going to invent a hatch-rate percentage for you. What the rails actually do is keep the egg in the pocket, pointy end oriented, so the turner can do its job. If your eggs are rattling around in a chicken rack, the rest of your “perfect humidity” routine is theater.

What to set, if you are setting this week

What we do have, and what matches the jumbo rails, is Jumbo Coturnix Brown / Wild-type hatching eggs — 12, 20, 32, or 42. The listing is honest about the growth target: birds reach jumbo size within 10 weeks. That is the line I will stand behind, not a fantasy hatch percentage.

Jumbo Italian is also on the shelf (12 and 24). Celadon too, if you want blue eggs and you already know what you are doing with that gene. Pick one size class for a given rail set. Jumbo in jumbo rails. Smaller eggs in the button/standard rails. Do not split the difference.

A short order of operations (so you do not scramble Saturday)

  1. Know your machine. CT60 = 12 rails. CT120 = 24. CT180 = 36
  2. Match rails to egg weight, not to the photo on the box. 14–18 g goes jumbo. 8–11 g goes standard/button.
  3. Drop the rails in and confirm nothing binds before you load eggs.
  4. When the eggs arrive, rest them point-down at room temperature before you set. Shipping rattles air cells. We already covered why we do not ship in plastic foam; this is the part that happens after the box hits your porch.
  5. Then set. Coturnix: turn through day 14, lockdown after that, hatch around day 17–18. Do not open the box to “check” during hatch. You already know that, and you will still be tempted.

What I would not buy for a dozen eggs

A CT180 is a real machine. If you are setting 12 jumbo eggs for the kids over Labor Day weekend, it is overkill. We also carry a Pro24 tabletop automatic if that is actually your scale. I am not going to upsell you a cabinet you will use twice a year. I will tell you that if you already own the CT cabinet, skip another gadget and put the $59.99 into the rails that fit the eggs you are actually setting.

Order the rails with the eggs this week. Let the holiday weekend be hatch prep, not a tracking-number refresh.
