Hi, all! I'm new here, but have had experience with chickens since I was a teen. However, this year I've run into something I'm unfamiliar with - hoping someone here can help! I picked up my order of chicks yesterday afternoon. This morning, I noticed a small lump on the right side of one of these little nuggets, below her neck, in front of her wing, behind her breast. I'm crossing my fingers really hard that it might just be a temporary vaccine reaction that will resolve itself, but if anyone has any experience, input, or helpful hints, I would be very appreciative! TIA!
