Hi lads, I went on the dark last minute and started the system on may 25th. Our first race is till the 3rd week of August and our money race is the last race of the seaso . How long do u suggest I keep them on dark for? I darken the loft at 6p and open up on 8am. The birds are just getting on a roll with the moult and I see plenty feathers in the morning. Any ideas and suggestions are welcomed. Bluebar
