I've been feeding mine on CSJ Herbie Rings for several months now and would recommend it to anyone. One of the girls is very fussy but has eaten this every day.
Their poos are good and no smelly wind
I reared a litter on CP27 and they were brilliant no sloppy poo and did really well.
I would recommend it to anyone - great price too.
Ceris who owns the company does run a sheep farm so is often very busy but she will get back to you.
