Feed conversion to egg output ratio-best breeds?

[carolynm]

Never, ever let layers run out of feed. Them not having feed in front of them for even an hour or two can put them off laying for several days. Normal laying hens don't get fat, even with free choice feed. A bird that does get fat should be culled.

Grown layers will eat somewhere between .25 and .4 pounds of layer ration a day, depending on breed, condition, whether or not they range, and how good the range is that they're on.

Do you know if that applies to ducks too?

Has anyone here ever evaluated bantam vs large size hen laying output? They wouldn't be popular with commercial producers because of small egg size but I'm wondering if a couple good laying bantams are better than a large fowl hen?
