Experienced and leading supplier of pigeon products since 1993

Harkers Ltd is the sister company of Petlife International Ltd, a family business, run for the first 25 years by John Hancock and his two sons, James and Tom, along with Pauline Muirhead the Accounts Director. Very sadly and tragically in November 2019 John Hancock passed away from a rare aggressive form of cancer. His eldest son James now runs the Company.

Harkers is the leading supplier of pigeon products and has been in existence for over 60 years, and with Petlife has been trading for over 25 years. In this time Harkers has become the leading brand in pigeon care in the racing world, specialising in a range of treatments including health supplements, preventative medicines and loft treatment. The company is well respected for its comprehensive line of products to help the pigeon fancier get the very best from his pigeons.

We sell our products through a large distribution channel which includes pet charities, pet wholesalers, pet retailers, vets and veterinary wholesalers, as well as some direct sales to the consumer; in fact anybody who has anything to do with animals!
