What age do these breeds start laying eggs?

[Hegatha]

I have Barred rock, EE'S, Cochin, & Polish?

I believe they are all pretty close to the same, 18-20 weeks, each chicken will vary of course, but I think that is the general "rule" as it is...

i know cochins about 8 months.

 

[MandyH]

Approx 20 weeks except the Cochins are around 10 months.

Funny thing is there all almost four months and one cochin and one barred rock are getting red combs. It almost looks like the cochins close to laying lol.

I wouls say that they are close. When they start squatting when you are nearby, they are closer.
