When it was just A&R, the other always came to keep the sick one company, but it just seemed ridiculous to bring three chickens to the vet when only one was sick. We thought leaving two behind would keep them calm, and that the sick chicken would be kept company by us, problem solved. Apparently not. Maybe they'll be calmer when we go next Thursday. I must say that if she had to get sick, I couldn't be gladder it was after she trusted us, I can't even imagine how horrific it would have been if it was while she still didn't like us.
The vet didn't find anything particularly worrying, but respiratory problems in birds can escalate quickly. She'll be on one week of antibiotics and a few days of anti-inflammatories to make sure nothing gets caught in her airway. If this doesn't work then they might try and put a probe down her throat to see what's going on, I really, really hope it doesn't come to that.
I noticed Lumi outside (for about the fourth time) and went outside, picked her up, carried her through the shed and put her down. Though what I didn't realise what that I'd put her down right next to her escape point because within 1 second of touching the ground she was already worming her way under the fence again. I lost it, it was hilariously cute. We then pinned that section down too.
