No. I said "if" she just laid them she was breed (gestation period) 28bdays prior. Most likely was early. Hatching would be incubation.
Here's how you figure it....
Assume full clutch of 14 eggs when you bumped her on 4/19. That means she has been setting (incubating) for either 1 day or 27 days at that point. If you assume she was setting for 1 day when you bumped her, that would mean she started laying her first egg approx 15 to 16 days prior.... or around 4/3. Average breeding date prior to initiating nest (laying first egg) is 7 days prior... so figure her first breeding was last week of March.
Now if you assume she was on Day 27 of setting (unlikely, as she probably would not have left the nest during lockdown (day 25 thru 28 of incubation) and you would never have known she was there), using the calculations listed above, she would have bred end of Feb/ beginning of March.
As I said before, it's proven that AVERAGE nest initiation is end of April, 1st week of May, which means AVERAGE breeding is 3rd week of April. The reason for this is because of natural selection. Hens which breed extremely early, lay extremely early, incubate extremely early have poults that hatch extremely early. Poults hatched extremely early have a much harder time surviving as there are fewer insects to feed on, and usually colder temps which they are vulnerable to until they feather out. Mother nature WANTS the poults to hatch out mid to late June... when there's a bazillion insects available to feed on, temps have warmed up, and heavy spring rains have subsided somewhat.
