We have 10 chickens, 2 geese, 1 duck and 1 turkey plus 4 kittens in our yard. They have pretty much grown up together and the kittens know not to bother the geese or duck or turkey as those birds bite at the kittens if they come too close. But lately we have been opening the chicken yard gate and letting all the birds free range in the whole yard so the kittens decided they could now go in the chicken yard and chicken house. So far all they've done is drink water and sleep in the hay and they haven't even tried to bother a chicken but we're concerned that as they get bigger, and that hunting mode of the full grown cat kicks in, that we'll have problems. Anyone have experience with this?
