I've done LOTS of incubating with usually no problems, but this year I've been having some issues with splay legs and deformed/missing/turned in toes. It started out with shipped eggs, so I figured they might have gotten a bit scrambled in transit. But some of my own hen's (two separate bantam breeds) eggs have resulted in the same. My temps are very constant in bators I have used for years. What could be causing this? Humidity? I am in a different location, but in the same area. Other than this issue, most babies that hatch are perfectly fine. All of my standard size hatches are fine, it's just the bantams (cochins, silkies, and OEGBs) that this is happening to. I run staggered hatches of all different breeds.
