Hi all! Bear with me, please...this is my first year with chickens as an adult. I got my second batch of chicks for the year last night. 5 Ameraucanas 5 Blue Laced Red Wyandottes 5 Salmon Faverolles 4 Cochins 2 Black Spanish Turkey Poults 2 Lavender Poults The two lavender poults and one cochin chick (all a week old) have crusty, brown, hard feathers on the front/sides of their necks. Is it just from dirty conditions, or is it more insidious? I've noticed a lump under the skin on several of the chicks' necks, that would be most understandable if I say it feels like an enlarged gland when you're sick. It's a little right of center...maybe it's the crop? I don't remember feeling it on my Barred Rocks when they were this small. (They're 4 wks now.) Sorry for the seriously novice questions, I can't seem to find answers anywhere. THANKS!!
