Next week I'm going to the local feed store and picking up 3 or 4 day olds. I got me a waterer and a feeder, a light. But now I'm looking into obtaining a box to rear them in. How big of a box should I use? Could I make a cage out of the 1" hex fencing I bought for when I make the coop or would that be too drafty for such young chicks? Also I'm looking at getting a Barred Rock, EE'r, and Silver laced Wyandotte. Is there any useful tips on sexing of day olds of these breeds? The store gave me their ordering form for the year from the hatchery they use and all three of these are listed as pullets, but how accurate are they for these breeds? And I'd like to double check.
