How much should a 6-7 week old chick eat?

[Sakai]

Weigh her, then start with 2-3% of her body weight. If she tolerates that well and does not vomit you can increase a little at the next feeding. The most I give is about 5% of their body weight.

2 ml to 5 ml per 100 grams of body weight should be your target amount.

Thank you! I have been weighing her, so I can keep track of her growth compared to her siblings. Today we gave her 14ml and she is about 340 grams. So that works out well. We'll be giving her another 10-15 ml tonight.
