Well, first egg was laid April 9, 2017. Do not try to calculate the day of birth, I will do it for you.
36 days from April 9th = May 17th, which is this Wednesday.
42 days from April 9th = May 23, which is next Tuesday.
The eggs will hatch in the order in which they were laid. The eggs were each laid 2 days apart.
Sometimes the 3rd hatch-ling does not survive because the older chicks usurp all the food; just letting you know.
Wish me luck,
