Trombe wall solar chick brooder was developed for 150-200 birds’ capacity. System evaluation as well as stability and equilibrium analysis were carried out. A set of linear differential equations were formulated that described the dynamic modeling of Trombe wall solar chick brooder for optimal poultry production. The descriptive models were referred to as system control. The model was transformed into Jacobian matrix andsolved for stability and equilibrium. Further tests for stability using Routh-Hurwitz criterion were conducted. The solved Jacobian matrix had negative eigenvalues and as such was locally stable. Routh-Hurwitz criterion affirmed that the system model was stable. It implied, the system supported brooding of 200 birds for the 28 days of brooding operation at temperature range of 25-39oC of the brooding room.
