I bought 2 chicks about 8 days ago and the guy I bought them off was throwing away fertile eggs since he had too many so asked if I could have some and he gave me 24 of them and put them in my incubator. They are at day 8 today and I was wondering if anyone could help me identify the eggs and what chicks could probably hatch from them, I’ll also send pics of some chicks that the guy has hatched out of some of the eggs but he had a large range of breeds so I’m not sure what I’ll get. The top pic(s) will be my 2 chicks that I bought from him, maybe some help identifying their gender as well.

I’m worried that this austra white is a male since both my chicks are the 2 1/2 weeks old and this one is bigger and has bigger legs and feet and it’s comb has grown since I got it and the others hasn’t

I’m pretty sure this is a girl since it’s a welsummer and it has the patterned feathers of the females and it has smaller legs feet and comb than my other chick

These are the fertile eggs out of the 24 I got, some are such a light cream colour that it’s almost white so it’s hard to see that in the pic

The top one is white and the bottom one is a light cream

The one on the right is the biggest eggs I have so I’m curious about this one

My temp and humidity on the incubator aren’t correct so after a lot of tests I’ve managed to figure out the temp and humidity my usingall 3 of my gauges, it looks complicated but I understand it

These bottom pics are some of the chicks that the guy has hatched out of some of the eggs he gave me, this might help figure out what eggs I have

So any idea on what eggs I have and maybe what gender my white chick is?
