I want to post these I bought these eggs from someone I received 16 blue copper marans, Of the 16: four were liquid or not viable due to shipping or who knows. seven had severe deformities beaks crossed so badly they look like someone broke them, brains sticking out of the skull, missing skull, no eyeballs and no eye socket. I contacted the seller stating that I am not looking for a refund or more eggs just hope this will help her with the breeding program. The seller told me my incubator must have spiked a temperature and that causes visual and hearing defects. It is my understanding that visual loss and hearing loss can be due to temperature spikes. These chicks did not have sight or hearing loss they were missing body parts. From what I have read this is genetic. I cried and got sick through the hatch today. When I hit chick number four with the deformities I got out the camera. There are two chicks living that have severely narrow heads and I am certain they will die. I cannot cull any more and my husband is out of town till late tonight. It is hard to see the missing eye sockets, eye balls.
