One chick about to hatch

[Espresso25]

I’ve got a single chick about to hatch. I have some 2.5 weeks old chickens, but the second batch only one egg took.

I’ve not got a separate brooder - the older ones are still under heat. How do I introduce them please?

Have you resolved it? How many 2.5 week ones? If not too many, I’d try them together and keep an eye.

Four - that’s what I’m going to have to do

The big ones will be ok without heat in the day so I’m going to put them in a cage (hamster cage) next to the little one and put them all together at night I think?
