Since she had 2 possible eggs that you feel had broken inside, giving her the enro might be a good idea, since most things I have read say that treating any reproductive infection early is key to it helping to prevent salpingitis. I will let you decide, but you will need to toss her eggs for several weeks until the medicine is no longer in the egg. I am very glad that he shells have become strong, and I would just make sure that she is taking enough crushed oyster shell. D3 is found in egg yolk, so you could feed her a bit of scrambled egg for some extra.
