Baby Bantam cochins not gaining weight, normal?

[Blessedmamaof3]

So I have 4 cochin chicks (3 bantam, 1 standard) that are 11 days old and the bantams are not really gaining weight. They seem ok and healthy otherwise. They have a heat plate in the brooder and don't show signs of being too hot or cold, they all eat and drink, though not nearly as often as the standard. They are not lethargic and run around fine though do stay under the heat plate a little more than the standard (1 in particular doesn't come out as often). I gave them nutridrench for several days to give them a boost, then decided to switch to corid, (i saw one slightly abnormal poo). How much weight should I expect bamtams to gain in 11 days time? Anything else I can do for them?

I've never weighted chicks. If they are acting fine I wouldn't worry. Bantams don't have as much growing to do as the standard breeds do.
