Got out first egg out of 10 BR pullets last week. They are my oldest at 21 weeks today. Then over the next 4 days we got two more. None of those were laid in the nest box but they were perfect little 33-34 gm brown eggs. This morning one was laid in the nest box I left it to encourage continued nest box use instead of coop floor use. Went out a little while ago and another pullet had just laid an egg in a different nest box and another was sitting in another nest box. It's really nice outside but every single chicken I have (24) is in the coop watching all the egg laying. They are so funny.
