Wondering about different hatching times with ine incubator

[Pollmadoll]

This is my second year hatching. We were really successful last Spring hatching a peahen called Blue, a silky serama cockerel called Woodstock, 2 Silver paced Wyandottes hen and cockerel now parents to be for chicks hatching this weekend. We have three due this Sat and two four days later. Will it be a problem ?? With lockdown and raising humidity levels?

4 days shouldn't be an issue, just go with what the first to hatch need.

Yep thats fine! You can stop turning eggs when they are 9 days from hatching if you need to.

My worry is upping the humidity for the others to hatch. Will that not harm the other later eggs ?

Not as long as they have decent air cell size.

I put the first batch of Wyandotte eggs in at 8pm Saturday , three weeks ago when is it likely they will hatch? Also when should I start lockdown

Chicken eggs take approximately 21 days, give or take a couple days depending on temps.

'Lockdown' is usually done on day 18.

High humidity four days early would not bother me.
