Oh dear what have I got myself into. This is my first go with broilers. I lost one on arrival and then a 2 more at night time. Since have learned that they need dim light all day and night to stop them from smothering. I have not lost anymore since. Since day one they have had the pasty butt. I clean them and it keeps coming back. One is so constipated that I even did a manual evac of her poop. ( I used to be a veterinary technician) I cant get the diarrhea to stop. I dont want to give antibiotics because I really want natural birds. Am i being stupid? Should I just give it to them regardlss? They are being kept in a insulated room in a garage. They have two heat lamps. The temp is 80 degrees at the furthest corner of the brooder. Its large, they have lots of room. They are on shavings. Two waters, two feeders. I am giving vitamins and minerals. And then tonight i heard a couple sneezing~ HELP!!!!
