I have 3 chickens total. One hen is a year old and doesn't lay. I have been feeding her layer pellets but no luck as far as her laying. I also have two younger birds. They are 9 weeks old. One is a rooster as I have recently found out. I have been feeding them grower pellets. Now I have put them in with my older hen. I am now feeding them all the grower pellets because I have read not to feed the younger birds layer pellets until they lay. Is my older hen losing out on anything by eating the grower pellets, even though she doesn't lay anyway? And what about the rooster? When my other hen is of age, I will want to feed her the layer pellets. Can the rooster eat the layer pellets too? Do I need to feed each bird something different and if so, how will I ever keep them from eating each others food? These are my pets by the way, so I don't mind that the older hen may never lay, but I wouldn't mind some eggs if the younger female will produce them.
