just like to point out the importance of black minerals and sodium/salt especially while breeding we put a egg cup of black mineral and a tea spoon of fine table salt for every 6 pairs fresh daily ...don't use rock salt or granulated salt as they could overdose on that best to get it in the loft when they are sitting ...ever had stock birds searching for something in the loft ? well their looking for salt very important for breeders ...salt licks are good to if you have a flight ....happy breeding
