Chick growth chart?

[UrbanEnthusiast]

I just got my first chicks, 4 brown Leghorn, 2 Ancona, 1 blue Hamburg, 1 EE. All small LF breeds, not bantams. About how much will they weigh at one month, two months, three months? I'm probably going to need to expand my brooder, just need to know when and how much.

If they grow like mine did, you can basically add a chick-sized portion of mass every week. So, they'll double the first week (x + x = 2x), second week (2x + x = 3x), third week (3x + x = 4x), and so on. It was just a rough estimation based on how they looked...I didn't actually weigh them, but you're more interested in how much space they take up anyway.
