I recently got 6 chicks, and on Saturday evening, I noticed one of my Rhode Island Reds was having trouble walking. She wasn't growing quite as quickly as the rest. She is about 2 weeks old today. I seperated her from the rest of the chicks, which I have been keeping in a 4'X4'X2' brooder box (w/heat lamp) inside--they have been bedded on pine shavings w/medicated chick starter. I moved her to a seperate box w/her own lamp, and she kept falling down and flopping over on her side, not able to right herself. After reading some threads online, I built a small chair for her, to hold her upright. She eats, drinks, and goes to the bathroom. I just noticed today that her rear is swollen and red. She does not have any visible signs of injury, and I wonder if anyone has had a similar problem, or might know what is wrong. Don't know if the rear swelling just has to do with the fact that she is in a chair? Please help!!!!!
