We've just used an incubator (hatching hens eggs) for the first time. We're on day 23 and only one egg has hatched. We (including our children) were delighted with our one precious little chick, but have realised its legs aren't quite right - one seems a little longer and is dragging, so that she's struggling a little. We used a digital fan-heated incubator, but it doesn't have anyway of checking the humidity. I know this isn't the natural time of year for hatching, but we wanted the chicks to be big enough to integrate with our other two hens by the summer, if possible. Could anyone tell me what we might have done wrong? We would like to try again. Thanks.
