Hi everyone! My name is Tina, I am new to the forum and new to chicken raising! I currently have four cutest RIRs, they are about 2-3 weeks old. They are really active and eating well, I am feeding them medicated chicken starter. They keep trying to fly, it's so cute. One even managed to jump all the way to my brother's shoulder when he bended down. I am posting because I am not sure if the following are normal chicken behaviors, please tell me if I should be concerned and doing something: 1. They have been scratching a lot more lately and picking off each other, kinda of reminds me of what monkeys do when there are lice on each other. It's not violent when they pick off each other, the other bird would just stand still, usually quietly too. 2. Two of them occasionally sneezes not continuously just occasionally. I think this started right after we had a quick shower and they were outside. The shower was so brief that it stopped by the time I got outside. The grounds where only damp, not wet. Note: it's been quite hot where I am, above 30C, so the chicks have been free-ranging in a chicken tractor in the backyard during the day. They come into the house around 8:30pm, peep madly for 30 mins before falling asleep. Though I have to say peeping time is decreasing daily.
