i change my feed a lot to get it right over the last 3 years its changed every year was on small seeds etc but now changed to super moulting it has 16 different seeds on it everything u need they stay on that all year yes i do mix things up with cocks and hens sometimes i do leave hens in with cocks for 5 to 6 hrs on friday and on return from race untill sunday morning and never go eggie its all about tweeking it to wat suits you ive raced widowhood natural etc but celibert is ten times better in my eyes no problems if u lose the cocks hen as never had a set one in start plus i think cocks get bored with same hen all the time its all about motivation for condition and fitness no other system will touch celibert for fitness
