Hi all.. I have a small backyard flock and hatch out babies from eggs I purchase. I haven't brought in any new birds that weren't babies. Unfortunately a few weeks ago I started losing birds... all younger (5 weeks or less). I keep babies up to 3 weeks old on my porch in guinea pig cages as brooders. Then they move to an outside hutch. (one is elevated with an open bottom, the other is on the ground with an area they can scratch at the ground) We are in Florida so heat lamps aren't necessary as long. The all eat Medicated chick starter and drink from large water bottles. SO.. the first issue started a few weeks ago. I noticed two young birds all puffed up (with feathers), looking miserable in the ground pen. I thought either bad feed or coccidiosis. (I did see a small amount of bloody poo) By the time I got home with new feed those two were dead. I treated with Sulmet as per the directions. Didn't lose any more from that group but a couple of slightly younger birds started looking off so I treated them as well. Lost a couple of younger birds. Noticed some mites, not many so I am using DE on babies and put Ivermectin on adults. Cleaned baby pens and feed/water dishes with bleach solution this weekend. NOW, I am still losing babies (all 2-3 weeks old) They just seem to stop eating/drinking, look miserable and in a few days die. Someone please help.. this is making me CRAZY!! I am losing about 1 a day which I know isn't a terrible amount but it's still frustrating.. I can't keep all of these babies and I can't sell them until they are well... Thank you!!
