Hey everyone. I am new at raising chickens and right now I have my first 3 chicks. I was told that they are baby reds, which I'm guessing means Rhode island reds (Unsure) & are around 3 weeks old. 2 of the chicks are completely fine and have grown a lot recently and are getting their feathers. But one little guy is just not growing at all and also has other symptoms. He hasn't grown, hasn't gotten feathers, breathes heavy, chirps loudly at random times, lowers his head a lot to the point that he losses his balance and falls, has had crusty white build up above his beak (although I was able to wash it off) and often has his eyes closed. He eats, drinks, poops, and walks around with the others just fine. Was told maybe he has mites but wouldn't the other two have it mites as well[/IMG]? The other 2 show no signs of anything bad. What is wrong with my poor little guy?!!! Just so worried I'm going to find him dead one day Side note...2 of them have black beaks and feet and one has yellow feet & beak. What does that mean since they are all the same breed? Thank you so much everyone!!
