I'm thinking ahead here ... my three will be around 20w, 16w and 10w when our 2 Pekins join us. The Pekins will be around 7-8 weeks. Will they be needing different foods? How long can I leave my older chickens on growers for? The Orp (eldest) won't lay, I believe, for many months so can she continue on growers? The New Red Hamp (youngest) will be fine on growers. But what about my Buff Sussex (who will be 16w then) and presumably within a few weeks be ready for layers? If I put them in different dishes will they just not eat everything that's out? I can't separate them - only one henhouse and run area. Grrr. Any suggestions oh wise ones?
