Hello all - just went out to the coop tonight and found one of my new OEGB pullets (got it 10 days ago) very weak, empty crop and also she seems very thin, not eating and sitting all puffed up. They had previously been free range and I put them into a large aviary (about 150sq ft) - she is one of five. Could she have been not eating because of stress? The others all seem fine. I had noticed that they aren't eating much but as they are so tiny I haven't been concerned. I'd be very grateful for any advice. Thanks.
