Yes, I have noticed that she had the red unusual stuff around her beak too. We have just taken her and another chicken Red to the vet today, we will know tomorrow.
Feet started bleeding from the black swellings and I imagine she was quite pained.
I was trying to soothe her with a mix - a maceration in canola and soybean oil of herbs - tinderbox gut tea - which has the soothing herbs such as chamomile, freshly ground cloves dried overnight pre-maceration for numbing and antibacterial and antiseptic, cinnamon powder which also is antiseptic, and essential oil peppermint - fresh, cooling and good for skin ( I just got more supplies for my new aromatherapy and herbal online shop! ) Also combined with freshly ground plant - comfrey leaves. Apparently a very good skin treatment for ulcerations.
I added hand sanitiser to preserve the oil, being ethanol based, and to max up the germ fighting properties!
