My last chick to hatch has just hatched a day late, the incubator has been kept warm and humidity and conditions are perfect, it just seems as if she has struggled with zipping. Before I left for a walk, she was pipped and struggling to zip, when I came back only 10 minutes later the egg looks to have completely shattered, as there are small pieces around unlike the usual two halves. Baby girl is out but struggling to stand, she keeps falling over to her back, cheeping but she seems very weak. I'm sure it's not a leg issue, as I have seen this before and this chicks legs seem strong. Any suggestions? Am currently sat watching her in the incubator struggling. Thank you x
