Had a pullet from my mixed flock lay her first egg today. I've only got 1 other one laying right now and I know it wasn't her since I'd just taken her egg in the morning. Whoever it was layed it right after I left in the afternoon to pick blackberries. The little stinker. It had a pretty thin shell and funny speckles from the inecperienced sprayer. Hehe. They've been getting layer feed. I started the oyster shell as soon as I saw this fragile little thing. How long does that usually take to work?
