My BR's started laying at 20, 22, and 24 weeks. My white leghorn I was told would lay at 16 weeks still isn't at 22. But my BO who was supposed to mature slower and my EE are laying before the LH at 22 weeks.
I have a bantam Welsummer. She is still too young. But I am enjoying her and even thinking of adding more in the future
One way to tell is when you quickly move your hand over the top of them, they will squat if they are getting close. However, like with many other things, some just won't cooperate. I also usually hear a practice egg song in advance. When those two things take place they usually start laying in 2 -4 weeks.
As we get later in the year, it's also possible they may wait until early next year. However, many of mine still seem to be starting up right now that are within a couple weeks of yours.
Good luck. Waiting for the first eggs from each girl is so hard!
Yeah, I know it's an individual thing, cause I have found my different breeds lay at different ages. Ameraucanas lay early for me, like 20 weeks. Wyandottes and production reds lay about 24 weeks, and then large breeds like rhode islands and orps take like 26 weeks. I was just wondering about welsummers.
