The week following the first two weekly procedures, her abdomen was filling up again; and she was starting to waddle and stand up straight. And so I went in with the needle, and pulled nearly 70cc of fluid again. This time though the hole didn't leak anymore. I tried to extract some more with another needle insertion, but nothing came out.
She seemed not too bad after that; but over the next several days, she was still walking quite a bit upright; and on the third day after the procedure, she lost her appetite. It is my experience when chickens get like that, the end is soon. Regardless, I force-fed her some goat milk; and in the evening, she was eating some food scraps on the ground and chicken scratch from my hand, and even drinking the goat milk, all on her own. However, as I said, they're usually in a bad way when they generally stop eating; and by the next morning she was dead. The Lord was merciful in allowing it finish quickly.
I'm not sure what happened: perhaps I punctured something internally in her; perhaps I introduced bacteria or otherwise during the procedure; perhaps her immunity was low and she caught something; perhaps none of those. I tried to be as antiseptic as possible during the drainings, but perhaps something still got by. (Please also see some of the comments about using an antibiotic/silver.)
It's sometimes a little difficult when you try to care for something, and it doesn't work out the way you had hoped, or worse, you worsen the situation. Also with this chicken, I used to be able to "talk" to her by making chicken sounds; and she would respond, which was fun to hear. And it is just an animal, but it's also God's provision. Still, it was her time according to His will, and we're thankful she went quickly; for the allowing us the provision of her; and for what the Lord would teach us, spiritually as well as temporily.
Death -- eternal, spiritual and temporal -- are a result of sin, and my sin; and I try to be reminded of my sin when I'm around death. And that reminds me to plead the blood of Christ for His atonement as He is the only way of redemption from the wages of our sins.
May He continue to teach us, and we pray and are thankful for His guiding hand in our earthly pilgrimage.
