What is your humidity? The one with "crooked neck" If it is stargazing/wry neck there are vitamins you give for that. Here's a page on it if you are interested: http://www.theeggfarm.com/blog/2011/11/02/wry-neck-in-baby-chick-video/Well, I opened my incubator and it's a good thing I did! Three chicks had externally pipped the shells but died trying to make it out! Four more were still living so I helped them out. 3 are completely healthy and one has a crooked neck. im going to watch the one with the crooked neck. It was having a lot of issues walking yesterday but today seemed stronger.
Since this was my second time hatching chickens I'm just happy that I got some babies at all.
Thanks everyone!
