Picked two sexed Speckled Sussex pullets up as mates for an older single chick. They are from Ideal, same age from same shipment, via the feedstore, something I haven't done much of in recent years. A week later, it's obvious that one is not growing the same as the other. Looks like its back is shorter. Its wings look way too big for its body, too, and its legs are like toothpicks, so thin. It eats and drinks, but is much more lethargic than the other one and chirps quietly a lot. What do you think? Is it going to make it? Is it genetically weak?
