Sebright color crosses?

[NatJ]

out of curiosity, if I make a coop in woodworking class, how big would it need to be for 15 or 20 Bantams?( Sebright flock of 10 ish, and some silkies for Broody/ incubation purposes. will probably start with 10, but plan to expand.)

Figure about 2 square feet per bantam in the coop, not counting the area occupied by feeder, waterer, and any floor-level nestboxes.

For 20 bantams, that would be 40 square feet of floor space in the coop. That is about 5 x 8 feet, or 6 x 7 feet. Bigger is not a problem.

If you put feed and water in the coop, add a bit more space for them. Since you want Silkies, and they probably cannot get to raised nestboxes, add space for floor-level nestboxes too. Many materials are 8 feet long, so you might just make the coop 8 feet each way to have 64 square feet.
