We decided to add to our flock last month. We had eight homebred chicks that were about 4 weeks old. We bought chicks and pullets as old as 4 months old to expand our flock and have four of the homebreds to a friend of ours. After a week or so, he said they looked sick and died. All of the four we still had looked fine, and he thought that his might have eaten something that they shouldn’t have. That was about 3-4 weeks ago. We noticed that two of our new chicks and a pullet hadn’t really grown compared to the rest, but didn’t act sick and we’re eating and drinking well. Our four homebred chicks free range, and one night when they came back in one looked like it didn’t feel good. They are normally very active and when we let them out earlier they all looked normal, but this one looked cold and lethargic. It was walking around with droopy wings and it’s feather were puffed out. The next morning we found it dead. Not long after we noticed that one of the chicks that wasn’t growing had bumps on either side of the corners of it’s beak and the pullet had an eye that looked swollen shut. Someone told us that they had fowl pox. This is the first time we have ever dealt with or heard or fowl pox, but we naively thought that it was like chicken pox, would run it’s course and everything would be fine. It did spread to some of the chicks, but other than bumps they all seemed to be doing fine. Fast forward to this week and we have found a dead chick or pullet each day. Some had bumps and other did not, but all died within 24hrs or less of showing signs of being lethargic. They have a lamp to keep them warm, but they’re kept in an XL dog crate inside our coop with chicken wire on the sides of it, so they can’t squeeze out. We put electrolytes in their water each day and they are on medicated chick feed. Yesterday the last homebred looked fine in the AM, looked unwell in the afternoon, and died a few hours later. We have lost non-home red chicks and pullets just as rapidly. Does anyone have any advice as to what could be going on? There is no discharge or sneezing or any signs of them being ill. They will just suddenly look lethargic and have droopy wings and poofy feathers and then die within 24hrs. Sometimes hours. We don’t know what to do and we don’t want to loose anymore. Yesterday we lost a cockerel that same way and he was in a water trough with a separate group of chicks and the night before he looked alert, but wasn’t being very active or eating and we found him dead the next morning. Any advice would be appreciated. Is fowl pox that deadly or could we have something else going one?
