How to Get the Sergeant Hen
What this page helps you decide: which egg to hatch for the Sergeant Hen, and how many hatches to budget before it shows up
The Sergeant Hen is a Rare chicken, tier 3 of 10 on the rarity ladder that appears in the drop data. 3 eggs can hatch it, and the best published rate is 11% from the Ordnance Egg — about 9 hatches before you should expect to see one. Below: every route in with the expected hatches worked out, where it sits among the 13 outcomes of that egg, how it compares with the other Rare chickens, and what we found when we checked the published percentages.
Which route is actually faster
The Ordnance Egg drops it at 11%; the Thunder Egg at 7%. In expected hatches that is roughly 2 times more work on the slower route. Both eggs come from chickens you can keep on the plot, so the higher rate is simply the one to farm.
Where it sits inside the Ordnance Egg
The Ordnance Egg can hatch 13 different chickens. The Sergeant Hen is the 4th most likely of them, with 9 outcomes sitting below it on the table. At that position it is one of the outcomes you are genuinely farming for, not something that shows up on the way to something else. Plan the session around it rather than expecting it as a side effect.
Against the other Rare chickens
There are 29 Rare chickens in the current drop data. Ranked by best available rate, 8 of them are easier to obtain than the Sergeant Hen and 20 are harder. Rarity labels are not difficulty labels: two chickens carrying the same tag can sit an order of magnitude apart in expected hatches.
What the published table does not say
These rates come from a single community index rather than the game files, so we checked the arithmetic before using them. 9 of the 17 egg tables do not add up to 100 percent — across the set they run from 91 to 102 percent. The Ordnance Egg table does add up, which is a small point in its favour. Rounded rates are good enough for deciding which egg to farm. They are not good enough for predicting any single hatch, and anywhere a rate is written as "under 1%" the true value could be several times smaller than the estimate above.
Step-by-Step
- Keep a Commando Rooster on your plot — it lays the Ordnance Egg, which is the source you can actually control.
- Hatch it repeatedly and budget around 9 hatches at the published 11%.
- Skip the Thunder Egg route unless the faster egg is out of reach — it costs roughly 14 hatches instead.
- Treat it as the target of the session; at 4th of 13 it will not appear as a side effect.
