Wishing you the best of luck and all the patience and strength in the world! You're gonna need it! The largest clutch of chicks I ever tried was 12 at a time. Thought I was going to die after about week two! And they were out in their coop!!!
Oh, and good luck on the revamping of their coop. Better not wait around for good weather. Those little babies grow so incredibly fast! You're going to need that space long before you hit the six week point.
Anyone wanna take bets on when the new chickies get their eviction notice?
