Hi! I have a small flock of 11 chicken all of which are 7 weeks old. One of the chickens I have seems very odd compared to the rest. She’s not feathered yet (she has some but not even close to fully feathered) and she’s quite a bit smaller than the rest of the chicks. She also acts a bit strange. All the other chicks run and peck and scratch like normal and she kinda just stands there or sits under the heat plate. She doesn’t run when you pick her up like the rest do. She’s just weird. I suppose she could be described as lethargic however she’s been like this her whole life. The rest of my flock seems very normal and they were all vaccinated at the hatchery. I can’t find anything online that fits except coccidiosis but she’s been vaccinated so I don’t think that’s the problem. Does anybody have any ideas? We love her and we baby her. We’ve kept her inside because she doesn’t seem ready to leave the brooder. I’d just love to know what’s wrong with her and if I can help.
