That's a great hatch, chickenwhisperer! I just ordered 42 hatching Chukar eggs, myself. (A buddy of mine wants to train his hunting dog, so he bought the eggs and feed, and I'm doing the rest for half the finished birds.)
I've successfully raised chickens, guineas, and ducks (coturnix quail in the bator now), so hopefully Chukars won't be too different! I'm planning on feeding them game bird starter (30% protein, medicated) for two weeks, then half-and-half with Purina Flock Raiser (20% protein, unmedicated) for two weeks, then switching to 100% flock raiser for the duration. I'll brood them in a big box for a week or two, then finish them in a 5' diameter (20 sq ft) stock tank.
I'm debating whether to try free ranging some Chukars with my mixed chicken, duck, and guinea flock. The guineas range far off, then come home to roost, which sounds like partridge behavior. Or I could treat them like quail in a cage or aviary. Hmmmmm.
Thanks!
