One of best breeders I now hatches from December all the way to end of September he just runs the late bred ones on and they catch up.... you'll after cull a littel harder that's all..... if your getten short legged fowl duckwing...... I would suggest upgrading your brood pens..... Remember guys don't over feed young chickens you won't them out hunting for there feed all day.... Stick with nature.... And cull ruthlessly...
