Hello I have a goose that may be having her first egg. I have been feeding mazuri waterfowl maintenance feed and have not yet offered oyster shell as she wasn’t supposed to start laying till summer. Just wondering what I should be keeping an eye out for in terms of egg bound and also what I can feed her now to ensure a hard shell. I cannot get oyster shell for another couple days so was going to crush the shells of store bought eggs but I came across an article saying that you should only crush and feed back to them their own egg shells and since this is her first egg I don’t have any to crush. Also is there anyway of knowing if she is actually going to lay? Thanks very much. Any help appreciated as I have no clue what to do.
