With the plastic I was concerned about BHA and most of them don't say on the bottom if they are safe due to hot sun and coop leaking toxic chemicals in water.
Thank you I never thought about keeping them off the floor. Will do.
Update on my sick bird, Airabelle. First I want to thank you so much for all your expert advice. Took her to the vet, she examined her poop, seemed to be okay. She said she may have Marek's disease or lead poisoning. She has been vaccinated for Mareks, as we know, have nothing of lead around or in the coop area. All other birds are healthy.
She said possibly the bird was missed when vaccinating or she may be in the 5% that the vaccine didn't take.
She administered Hypericum which is an homeopathic herb for 3 days. If no improvement then chelation therapy for lead using medication for 2 weeks. It's expensive and not full proof.
I think we may put her down and not put her through the therapy as I've read it's hard on a chicken and can be fatal. If we put her down we will refrigerate her and take her to those centers to find out what the cause was.
Does anything make sense with the veterinarian's diagnosis to you?
I have gone through this scenario recently as well. You can have a metal toxicity test done (lead/zinc) via blood sample, which can be sent overnight and you'll get results fast. Mine took three days total. It was not inexpensive, but it was still less than the chelation therapy and it gave us an answer for sure. (mine came back negative for what it's worth)
What are your bird's symptoms? Maybe start a new thread if you'd like. There are some of us here with Marek's experience and maybe we can help. It won't substitute for a knowledgeable vet but it's something. There's also a link in my signature that can get you started reading about it. Marek's vaccination is not quite 95% as 'advertised' anymore, due to the variables of genetics of the bird, vaccine(s) used, strain of Marek's, etc.
