this issue is not related to MCPE-12516. it is a baby chicken only bug. if it were related to MCPE-12516, then it would be resolved. it is still in 0.15.6.
set out a dispenser with a lever. set a cauldron next to it's output and cover it with something like a carpet. put a spawn egg in. if the egg spawns an adult, it will stay in the cauldron. if it spawns a baby, the baby will jump out. if you were to put lava over the cauldron so that when the baby grew it would be cooked, it doesnt work because the baby always jumps out and dies.
