Hey y'all! I'm a total newbie and literally know nothing about chicks /chickens! My boyfriend and I decided we wanted to get a few chickens for fresh eggs, and we wanted to get Easter eggers cause of the fun colored eggs. We picked up a couple 3 week old chicks yesterday from someone we found on craigslist. They're Easter eggers mixed with a lavender amaraucana rooster. Most of the chicks are missing feathers on their wings and under them but one of the little guys is pretty much bald from the neck to tail. The skin looks a little dry/flaky and has a yellow tint to it but not red or bumpy. They're also scratching their head and shaking. The guy we got them from had a bunch of little chicks in a small area and they were all walking on eachother. He says the feather loss was due to the chicks stepping on eachother but I just want to make sure it's nothing to worry about like mites/lice....could they me shedding their baby feathers and getting their big feathers now? Right now they're black and he said they're going to grow up to look white. Here's what they look like right now.... We went down to the local feed store and spoke with the lady that owns it she said it sounds like there were just too many chicks in a small area and that if it is mites try diatomaceous earth. We picked up a bad of food grade diatomaceous earth and she said to sprinkle some on them and in their food. Does that sound about right? We also got a bad of chick starter/grower food is that the right kind of food for them right now and is that all they need to eat? Thank you all so much. I know about cats/dogs but totally clueless about chickens.
