You use supplemental lighting, right?The girls didn't let me down. 20 weeks today & I got my first light brown spotted egg! Not the perfect pullet egg exactly. The pointy end is rough & has a small hole in it. They keep moving the straw down to the wood in the one box. I love it anyway. I would guess it is from a Partridge Rock, but there are 2 Australorps that look ready too. I had a Rock lay a soft egg with only white yesterday. Here's hoping I'll soon be over run with eggs!
That can make a difference, especially with pullets that are still a month or more from the average onset of lay. I started my chicks late this year so will be using the lights so I don't have to wait until spring.
