My billy goat is only 2 years old, and i dont know whats wrong with him. he will be fine one minute, but the next his legs stiffen up and he lays on his side and kicks hard and tries to get up but he cant. it breaks my heart to see him so helpless. he still eats and drinks his water. does anybody know what this is? if so, what can i do for him? if anybody is knowledgable about this, my email is: email@example.com. any info will help!
