I have a near 3 year ol hen who started having weird bumps thats appeared to be part of the skin of the foot. It broke throught the scales and under her feet too. I thought about bumble foot but it was on the sides of the feet too. she walks in a sort of a stumble and soon she started to pick at theblisters when they sort of popped. I regulary soak her in hydrogen peroxide and put tea tree oil and bandage up the wounds because when she picks they start to bleed a little. The rest of the five in the flock have seen her weak and peck her. This has come to a a dangerous point and we closed off a space in the coop for her so she won't get pecked when we are not around. Any ideas on curing this foot problem? Thank you for reading this.
