Dead birds are just found by happenstance on the ground. Usually foxes or wolves kill some of the nearby chickens or foul and leave the corpse for you to scavenge from. So, the number of handbaskets . . . it all depends on your map and how limited your resources and time might be once you find cattails. Cattails can be very scarce in some areas and you really want to ration it out across each day in order to make sure that you don't run out during moments when you need it the most. If you have lots, no problem, make as much as you want (within reason lol). Yes, the haybales keep monsters and animals from entering. I was skeptical of this at first, but yeah, it works really well.

And here is what the design would roughly look like if you try to do it like YoardaEatsMellon did above in the article. Stuff isn't quite to scale, but this is the general concept.

Here is another way to visualize the construction, in case any of you find it to be helpful. It's not 100% identical to YordaEatsMellon's design, but it's close enough that it demonstrates the basic idea of the A-frame style house. If you want to see what Yorda's design looks like, check out the image I posted below.
