We went out yesterday to feed and water the chickens and two of r chickens were dead, they wasn't acting sick or anything before so we had no idea what happened to them. Then we went out this morning and are rooster is acting funny and he's all puffed up. We went to feed them and got looking at the feed it it was molded. We throw it out and got new but what can I do for are rooster? My mother -in-law said that he was bloated , what can I do for the rest of my chickens , I don't want to loose anymore?
