We have 5 young pullets, approx. 4 months old, and one just seems to want to sleep all the time. We had 6, but have already had one die. This one, a RIR, shows very little activity. When I check on her, she is usually always sleeping, whether in the coop or out in the run. She does seem to eat okay, but otherwise hardly moves around. When she does move, I do not see any problems with her walking. I have not seen her drinking, so I have dropper fed her some. We medicated the water with Sulmet and I want to make sure she is getting some of it. We have also given vitamins and electrolytes, and are putting dewormer in the food. She seems to be losing some of the feathers around both eyes. Some of the other feathers were a little hard and looked wet at the tips. They felt like something sticky had dried on them. I don't have any idea what might be the problem and have no more ideas about what to do for her. Our other 4 seem healthy and active.
