I posted a thread about the leghorn I lost recently. Now I have lost two guineas. The leghorn was basically standing still and not responding, and the next day she passed away. Today I found a dead guinea in the coop, and one outside that was barely alive. His head was flopping back, he seemed unable to hold it up. By the time I had the playpen set up, he was dying. My main concern is that the three incidents could be related. Both the guinea and the leghorn flapped and spasmed just before they died. I could use a lot of help, as I have no idea what it could be. I will give them some electrolytes and probiotics tomorrow morning. Also, both guineas were males, and the leghorn was a hen. I don't know if that will help or not, just thought I should mention that. Please help!
