Hatch statistics
It has been suggested that it might be interesting to have the hatch statistics, even if it is difficult to extract any valid conclusions about broodies' abilities from them because of all the extraneous factors at play before and during incubation of the eggs. So I add them here; readers are welcome to share any impressions that they form from these statistics in the comments section of the article.
Breed acronyms: A = Araucana; H = hybrid; NG = Norfolk Grey; P = Penedesenca; RIR = Rhode Island Red; W = Welsummer. All the birds in the flock are large fowl.
Notes acronyms:

| Dorothy 2 RIR | 2019 | 4 | 3 | 1 NR |
| Eve 1 NG | 2019 | 4 | 2 | 1 EB; 1 EED |
| Eve | 2019 | 7 | 4 | 1 I; 1 DIS; 1 DPE |
| Eve 2 | 2020 | 10 | 4 | 1 DIN; 1 DIS; 1 EB; 1 I; 2 NR |
| Eve | 2020 | 4 | 2 | 1 EB; 1 removed from coop by broody – it was going rotten |
| Eve 4 | 2022 | 8 | 3 | 4/6 bought eggs and 1/2 home grown eggs infertile |
| Maria 3 A | 2020 | 8 | 3 | 5/6 bought eggs infertile |

| Maria 5 | 2022 | 6 | 2 | 3 I; 1 LED |
| Janeka 2 W | 2021 | 10 | 9 | 1 I |
| Janeka 4 | 2023 | 8 | 4 | 1 knocked out of nest day 5; 1 EB day 7; 1 DIN; 1 DIS while hatching |
| Paprika 1 P | 2022 | 8 | 7 | 1 DIS after partial unzip |
| Paprika 2 | 2023 | 6 | 6 | |

Notes acronyms:
- DIN = hatched but dead in nest, no injury; presumed dehydrated, suffocated or trampled
- DIS = dead in shell
- DPE = disappeared, presumed eaten
- EB = egg broke during incubation
- EED = early embryo death
- I = infertile
- LED = late embryo death
- NR = no record found to explain the failed egg
