Hi there! I have 6 easter egger chicks that are 6 weeks old. They have a chicken tractor and free range during the day. In the last two days I've noticed that the biggest chick has been laying down a lot and doesn't really seem too interested in foraging, though she does keep up with the flock as they move around the yard. Most of the time she's just laying near the rest of them while they eat and constantly grooms herself. She seems much more interested in grooming than eating, but she definitely drinks a lot. She'll peck around here and there but doesn't seem as eager as the others to find food. Her poops have been watery and contain undigested grass. She also still sleeps on the floor under the heat lamp with the smallest one while the others roost at night. I've inspected her for mites but saw nothing and her comb is still nice and pink like the others. I was about to take her to the vet ($$$) but after speaking with a neighbor, I decided to wait it out and observe more. Any advice would be so very much appreciated! Thank you!
