Last night Goldie was making no noises at all. Now this morning when I went to let the hens out of the coop, I heard a strange "hahhhhhhhh"(think of a regular chicken noise amplified in a long tone) and discovered it was coming from Goldie. She is acting just fine otherwise and is eating, drinking, walking around, etc. Her eyes are bright, comb healthy red, feathers as gold as usual. When she pecks for sunflower seed the noise stops almost completely. None of the other hens are doing this. If this is a sign of illness I need to know ASAP and what the possible cures are. If this is not a sign of illness, I need to know what else this could be. Please reply!
