Baby Chickens have buggy 'hit boxes', drowns from water 5.1+ blocks above but not lava at the same height

Baby Chickens have buggy 'hit boxes', drowns from water 0.51+ blocks above but not lava at the same height. They also get suffocation damage from blocks at 0.51 above the chick. This breaks many forms of Automatic Raw Chicken farms. This has occurred since 14w11b.
