Please help me understand what happened. It was my first hatch, the first time my Bourbon Reds starting laying and my first time operating an incubator. I started out with 9 eggs and continuously made sure that the temp and humidity was accurate as close as possible. (may had the humidity too high towards the end???) 3 poults hatched and I thought was doing great, very excited! But as they grew they started changing... one has a twisted leg, one has a twisted neck (side of chest) and the smallest one has gained any weight and has poor feathers. They're all are very friendly, loves being petted and loves being outside. They are a eating gamebird starter and have been since their hatch. Since then I hatched another set of eggs and had 7 hatch, they are 5 weeks and look really great. Pictures are attached. Tank you for any information and advice.
