I just received my new chicks yesterday morning from McMurray. I noticed today one had a swollen area on its neck. It is acting fine, running around and eating and drinking. So then I started looking at my others. Quite a few had that swollen area on their neck on their right side. After some reading I now know that is where the crop is where they hold food for digestion. Do you think they are ok and that its just from their constant eating and drinking? I just want to make sure because if something happens to them I want to inform the hatchery.
