Hello, I just wanted to take a brief moment to introduce myself and my flock to the group. I started my flock a year ago and have found many useful answers on this page so decided to join so I could share as well. I have 7 girls 4 buff orphangtons *sic* 1 black sex lynk and 2 no clues. I built "coup ma'haul" for my girls because as an animal lover I also have 4 doggo's who's passion for the chickens border on the edge of dinner bells. Of my 7 girls only one so far has gone broody on me, Chicky'Tiny has done this twice and this time when she came out of it she is mysteriously laying eggs with shells so thin it is more like a membrane only egg, not sure how she got that out without breaking it, the first one did get broken and subsequently eaten, no-no please don't start eating my fresh eggs!! I have oyster shell for them and give them layer crumbles with a seaweed vitamin boost so I need advice on what else I can do to harden up her shells. Thanks so much for the add and the advice.
