My 9 month old dewlap/embden cross goose laid her 4th egg since the 1st one on 2-14 today, it is a ping-pong ball size little round egg. She gets 16% protein layer pellets free choice, plus has free range of the yard during the day, lots of green grass/ weeds to graze. Was surprised she started laying so early at 9 months old. Do I need to supplement calcium?⁹
