I'm going to do it. From day 1. Even with the shorter days, I have a WC Polish hen who has given me an egg every day for the last 3 days. The one I got this morning, I placed under my breast. I'm keeping a written journal about this insane adventure. Mostly I'm checking fertility, but doing the bra experiment at the same time. I guess this sports bra is my new best friend for now. I will candle this baby at 5 days.
