I have 10 girls and just started laying crumble...only 2 of them are laying and the other 8 are about 20 weeks. They are molting so I'm guessing that's why they aren't laying yet??? I do not provide heat or lighting either. Why aren't they laying?!!!! Too cold? I live on cape cod and days are about 20-25 degrees and at night 10-20 degrees. Advice pleaseeee!
If your pullets are 20 weeks, they are not molting. They probably are just late starting their laying. Chickens don't molt until after a year of age.
