Out of the following breeds...

[AJ666]

which one lays first???
RIR
Buff Orphington
Domonique
or EE

 

[mississippifarmboy]

I've never had EEs so don't know about them, but our RIR and Buffs start laying around the same time, the Doms take a bit longer.
Others birds might be different though.

 

[Cats Critters]

I have only had 2 of the breeds (RIRs and EEs) and the RIRs laid first.

Your Easter Eggers may vary, but are sometimes later.

Your Production Reds, Dominiques, and Buff Orpingtons are likely to begin pretty near to each other, and pretty much "on time."
