Hi there, I’m newly joined but I’ve read threads the past couple years as I started my own flock. I noticed a couple weeks ago what looked like a mole on my hen’s beak or thought maybe she got a little poo on herself as they can from time to time. Unfortunately it has grown and I’m not sure what this could be. None of my other hens have this. I will add that beginning of summer I lost a couple of my hens and had one sent off per my vet to see what was wrong and it came back she had a egg crack in her stomach and tumors and mereks, since then I e lost half my flock. It’s been a very emotional heartbreaking ordeal, because I love them very much. I read some can be strong enough to only be carriers of it and live. With that being said this is a first, and I’m not sure if it’s from that or something else? Any advice would be appreciated. Here is a picture of my baby girl Dovey. I have never seen anything like this on any of my chickens.
