I have seen some big poults recently, half the size of the hens, and some really small ones in the same area, 4-5" tall. I am really amazed at the size difference and am wondering why? I did the math and figured the small ones were hatched around the 3rd week of July. Could this be a second clutch or just a late breeder. Mamma wasnt a jenny, she was an older bird. Just curious to hear your take. Z
