I just noticed my 3 week old chicks have crooked toes, well about 30% anyway. I'm sure this must have developed in the last few days. What's interesting is that only my BRs seem to have this problem (about 75%), not my BOs. This was my very first hatch and I may have done something wrong. Storey's guide says low temp can cause, but my incubator was pretty steady between 100-101 degrees. I'm starting to collect eggs today for a new hatch & want to know if this is genetic. I have 2 BR roosters and would need to determine which of them is carrying the trait. Any suggestions?
