I have 3 Sultans-2 Roos and 1 hen. How large are the standards and how small are the bantams? I ordered standard ones last year-so mine are 1yr old. My hen is laying a very soft shelled egg- it pops like a water balloon right now. They are separated (only 1 roo is with her-poor girl, I didn't want to have both of them with her) and have added grit and oyster shells to her feed. SO hopefully soon the eggs will be hard shelled. Will let you know if they are and I'll get back to you then.
