Chicks born from eggs thrown at a block, often suffocate within that block.
Oddly, I have consistently noticed that this happens far less (to the point of only rarely) if the egg is thrown at wood or stone (even maybe glass !? not enough data yet to be sure). If I didn't know better (and maybe I don't), I'd think that the increased density of these two materials makes the thrown eggs more likely to spawn outside the block as they should.
I realize this sounds kind of stupid software-wise, but I throw a LOT of eggs (around 300-400 daily) and this is consistently true.
Also: I always play in peaceful.
To reproduce this is simple:
1- Make up a large farm of about 300-400 chickens
Do this the usual way - mating intensively.
To check your population count:
a. Enter the colony - after all chicks have matured - with several FULL seed stacks...
a. Immediately and quickly feed them to full saturation...
b. Get an accurate count by adding the number of seeds it took to feed them.
2. Run around the coop a few times, collecting eggs, depositing them into a chest as you fill up.
3. Count the #eggs collected..
4. Locate / create a few dirt blocks at 4 or more blocks high and at an angle/area where you won't hit anything (i.e. chickens) when you shoot at it and so the resulting chicks will fall down into the coop.
5. Aim & throw half of the collected eggs at the dirt blocks, counting the number of successful chicks vs. dead chicks.
6. Replace the dirt block with another of the suggested block types (wood/stone/glass...) & repeat the test with the other half of the collected eggs.
Now you can create stats and report them using the collected data, if you wish.
I hope this unusual info helps you in debugging the problem. It's pretty annoying.
What's my release? I don't know how to check (I'm still a newbie in several areas), but everytime MC asks if I want to update, I do immediately. I hope that helps.
The same thing happens to NPC Villagers... not all of them (so far), but several despawn after being away from them for several day. I lost my source for the diamond pickax blessing of 'Looting II with Sharpness III' that way! Sorry, I didn't think to collect data at that time. Since it happens over a period of time, it's hard to know how & what data to collect.
Re: Can't hear them anymore...
THAT would be the one good thing that came from this. Their incessant barking (and cats' meowing and the other mobs chattering away) is WAY annoying to me. While I like hearing them, I despise hearing them so frequently! I hate to turn down/off the sound - I need to hear other cues from the environment. Wouldn't it be great if it were variable?
Thanks for this indulgence. This issue (the REAL issue of mobs despawning) & one other (mob babies suffocating upon adulthood) have my prickles up! Add the ever-present 3-5 fps LAG & I get positively LIVID.
Since MC is what I use to help me(via distraction) with my disease's Chronic Pain, you can see how very much this irritates me.
Can we PLEASE hear from the devs HERE about this issue?? ANY NEWS at all would be good to hear.
PLEASE! PLEASE! PLEASE!
thank you for this forum. I promise not to indulge like this again. i hope it shows HOW distracting/irritating this issue is & why it has to be addressed.
