The 2-3 week old RIR chick is not energetic at all. It seems to be sleeping, but with some difficulty breathing. Its eyes are always almost closed, except when its disturbed or when it hears a noise that scares it. It will not eat anything, it will not drink anything, and I have tried to feed it, without success. What they are usually fed is chick starter, and sometimes some bugs i find outside. The 4 chicks used to live in large box in the garage. We have a 75watt lightbulb there, on only at night, but the chicks dont seem to sleep under it, they sleep in the part farthest from it. The poop is not runny or looking anything suspicious. I do not know whether or not it is the heat, or a sickness, but i do not have any medicine watsoever, and i have no idea what treatment to give the chick. None of the other 3 chicks are looking like this, and they are all looking energetic. I have no picture, sorry, but it should be pretty easy to imagine. If a pic is really that necessary, i can put one on. There are no signs of blood, broken bones, or any trauma, just a tired looking chick. And the bedding that was used was pine shavings.
