I have 4 six-month-old RIR pullets and 1 six-month old rooster. I have one feeder in the coop, and I give my peeps layer feed (I think all of them are laying) and mix oyster shells in. Is it okay if my rooster is eating the oyster shells and layer feed, even though he is obviously not laying?
Also, when I get my new chicks in Spring, how will I get them to not eat the layer feed and instead eat the chick starter? They will be in the coop with the layers. Do I need to get another feeder? Will they know not to eat the layer feed?
