So I was just snipping Snows bum feathers to reduce the mess and I think I snipped a blood feather

She got down and I won’t be able to catch her again to try and put cornflour or something on to help clot.
Might try at roosting time. She is chickening fine and being a white chicken I feel excessive blood loss would be obvious.
I’m just really cross at myself and hoping it will heal ok.
Edited to say that I cornered her and lifted her up on a chair to check and it hasn’t bled a drop out of it and has seemed to have clotted for now. I will keep an eye on it though, make sure Belle doesn’t zone in on it.
Who said chickens were easy
