They have only been outside for 5 days. I didn't notice anything before they went out. I think about 3 of them have this out of 30. 1 is missing a lot of feathers on her neck. They are protected by a 4' tall electric fence and pallets. The roof is covered. Im just not sure what this could be. They all seem fine, but just a couple have these sores. They all appear to be in the same spot. Some have them on both sides at the same location. These birds are organic so I need all suggestions to be within my means. I'm keeping an eye on them. I saw this yesterday, and not much has changed since then. last weekend they were in my basement in a deep litter. I just don't know what they got into while outside for 4 days that would cause this. The land I put them on was just leaves and sticks. I'm in New Hampshire. They went from 65 degrees to 30's-40's. Sometime the temps dropped below 30. They are 3 months old. They are isa browns.
