Hello! We have 6 girls of various breeds that are 28 weeks old. Five of them are laying very consistently for a few weeks now, but our Dark Brahma, Dolores, is not laying yet. Her comb and waddle are just starting to develop and turn red, and she is already twice the size of the other hens. Should we be concerned that she hasn't matured like the others? Anyone else have experience with the breed who can tell us if this is normal? Thanks!
