Our neighbors are growing ostriches at the dacha. Sometimes we go to visit neighbors and watch the behavior of these ostriches. When they only hatched, then the size of no more than an average chicken. But they grow very quickly. They were observed often, and even a couple of times they bitten me, by the way it was rather painful. We were given a pair of eggs of ostriches for an omelet, so I did not get one egg into the frying pan!) And once the biggest ostrich got out through the barrage and so waved that they could not catch up with it, probably in the woods the wolves were glad to the guest). in general they have very tasty meat, but have you tried?
