I am here again! I had been losing some birds and ended up treating them with Streptomycin.. then I didn't lose anymore then a 2.5 weeks after a 4 month old Buff Cochin died He was acting off for a day then died the next day, while he was dying he couldn't stand and would fall over on his side.. Now I am wondering if it Merricks that they all have had?? None of the 4 that died had splayed out legs or anything like that, they got sick, weak and wobbly and died within a day or so..I thought cooccidiosis so bought Sulfa Methazone to treat the rest.. Only one other (4 month old Lavendar) is acting strange and it is doing a neck twitching/stretching thing.. Almost like if we were to get a twitch or a shiver, goes from its chest up to its head. It will stretch its neck out and twitch every once in a while.. I am going to look for my last post to see if its help you all help me figure to out!! Thanks so much! I am losing sleep over this , they are my daughters well loved pet birds!!
