I got three chicks at 1 week old. Two of them had very large heads that I thought added to their cuteness. Those two did not thrive. They stayed small, hardly grew any feathers and both ended up dying by 1 month old. The other chick with the normal head is growing like normal. Did the two chicks with the large heads have something wrong with them that has a name? Does anyone know why they may have died? Here is one of the chicks with the large head. She only lived about 2 weeks. Any help here?
