I'm not really sure what to do here. My chicks ages range 11-17 weeks this week and I'm pretty sure two pullets will start laying soon. They have red combs and face. I really worry about the young ones eating layer feed since they all eat together. It's nearly impossible to feed the 3 older chicks seperate. Will it be harmful if they eat grower for a month or so while their laying? I'm just switching off of medicated and into grower in a few days when the medicated starter runs out. I do know the young ones can not have layer yet due to potential health problems from too much calcium. Thanks.
