I just got my first batch of chicks two weeks ago. I got 2 silkies, 3 speckled sussex, 3 rir and 2 australtorp. They all seem to be doing well, doubled their weight in a week.
The sources I've seen say to provide chicks with a perch once they're 4 weeks old.
I'm wondering, why not earlier?
I build a small roost of 3/4 x 3/4 square wood, the chicks love jumping on and over them, and sometimes resting/sleeping on them.
Am I harming the chicks or creating future problems by having roosts at 10 days old?
