Fellow backyard chicken raisers, I need some help. Before yesterday my chicks were all happy, energetic and seemed comfortable with temp in the brooder. Last night I had one go down with pasty butt and get attacked. I tried to help it but wasn't much I could do. This morning I treated one for pasty but she is moving slow and blows up bubbles after she drinks. I put some sugar water in their drink as suggested by a member through another thread. about 20 minutes later my two remaining sussex started acting strange; hobbling around and one stretched its neck all the way back and flopped over. What has happened in the last 24 hours? Why are the sussex affected and not the other chicks? What can I do to help them?
