Does everyone clip their chickens toenails? If so, How?, as in, do you wait until night when they are roosting and pick them up, one by one?. I have 24 hens and some of them have very long nails. Others are ok. They have plenty of different surfaces to scratch around in, cement, dirt, grass, etc. Seems some of the very long nails are starting to deform their toes. How often do you clip? thanks
