Tiny pale eggs started popping up in the lay boxes?

[Allie Grace Sanders]

So, I have 7 year old hens that have been laying since month 4. I recently integrated 20 pullets who are now 12 wks old. I also added 3 ducklings who are 11 wks old. I have 1 BSL and 3 ISA browns in the pullet mix. The BSL's comb and wattles are getting bigger and getting redder. Is it possible for her to be laying yet?

At 12 weeks I believe it’s impossible to lay eggs... mine are at 13 weeka right now and are way immature. I believe it’s somewhere around 21 to 25 weeks that they start saying.

I know that it probably isn't possible but I just wondered if there was a chance.

I've heard of Red sexlinks laying at 13 weeks, do you have a picture? You would probably be able to tell if she has hit maturity.

Could be one the older birds, stimulated by spring and all those youngin's.

I seriously doubt it's the 12 week old...but

At 12 weeks, I worry that your BSL is another one of those mistaken identity cockerels.
