Almost 5 weeks - they hatched around 5/5.
I pulled two out that I know are males and one more that I am pretty sure I saw crow (I managed to get a conjunctival abrasion yesterday which is a fancy word that means I scratched my eyeball so it’s hard to see properly LOL).
There was at least one other one crowing while I was dealing with those three, but they’re being awfully quiet now. I know one of the two creamy colored ones is a boy, but those are the kid’s favorites and I’m hoping with the other three out he’ll settle down.
I should add, while they do occasionally crow (and one night at 1am one of them went off about something, I suspect a cat) they’ve never gone on for half an hour almost non stop like this.
I’m afraid the ones I pulled are tragically not going to make it to 6 weeks. I don’t DO 4am. Not for anything.

I’m sure the neighbors don’t either. I just ordered some poultry shears I saw recommended elsewhere and they’ll be here this afternoon. I’m hoping 1 week won’t make much difference here or there, we’re going to skin and spatchcock them anyway because I’ve only ever cleaned fish and even that was a very long time ago.
