I rescued a 3 yo brahma hen. she is molting. she had too many fleas when I got her. she is clean now, her comb is darker but her eyes are half closed. I have noticed that she does not see well. eating and drinking normally, no sign of any illness. but I can hear her breathing just like old, fat people do. her beak is closed, no difficulty breathing except the noise. should I be concerned? her comb is darker now than in pic. her eyes are like that all the time. I wormed her but it seems she didn't have worms. her poop is normal. I feed her 18% grower feed because of molting. she is not laying. skin around her eyes is yellow.
