Hello all we have 4 almost 4weeks chicks and they all looking great. we keep them in a 2'x2'x4' cage and we also have 2 Guineas also that are 2 weeks older. They all get good eating and drinking. The Guineas are the leaders, but a few of the Pea's give the Guineas a run for the money. We've been feeding them the chicks feed and just now week I've given them some green grass, and they go for that like they haven't eaten before. Question 1: when can I put them on the grass yard? we have 4 chickens that are 2 months old, but they stay in their cage mostly. Question 2: can the Guineas and Pea's stay in the same cages for several months/years?
