Day 4 into Hatch and another worrisome thought!

[lockedhearts]

We are on day 4 and now I begin to think, I am hatching Cochin, Auaracauna , BO and RIR together. My BO and RIR eggs are really good size , the aracauna are average and the cochin are small.
Assuming I have a good hatch (fingers crossed) will the Cochin Chicks need to be brooded away from the others due to their size? These will be pure Cochins since thats what my roo is.
Already worried and only day 4.......

Are they banty cochins? Or standard cochins? If they are standards, you can brood them all together.

They are standard Cochin's. I was thinking they would be ok, just got pre-hatch jitters
