I think my Gabby Duck is about 20 weeks old, and she has started laying. 5 eggs in 5 days. I've been feeding her and my goose the same diet-- Mazuri waterfowl maintenance, scratch grains, black sunflower seed and lots of greens. I provide oyster shell, and since her first egg I've been crushing up eggs and egg shells for her. Should I be doing more? Her eggs seem nice and hard and are getting bigger each day. Just want to keep her healthy. Thank you for any advice. Also, will she stop laying when fall hits or even before? or does it get more intermittent, but keep on all year? Thanks.
