I have 30 or about that many 20 week old pullets of different breeds. I have been feeding them chick starter/grower since they were 1 day old. And some veggatables and bread here and there. Just today I switched them to laying mash because I was told they need it to prepare for laying. But I don't think I'll be getting any eggs from them for awhile. What have I been doing wrong because they seem way undersize. There combs aren't even coming in very much. As you can see in the pictures they are pretty small.
