Little update: We finally got back the results of the crop swab (the delay is a long story

) and they found some gram-negative bacteria. El is just about at the end of the antifungal treatment now so I'll probably start her on the antibiotic on Sunday or Monday.
My only worry is that calcium is said to lessen the absorption of this particular antibacterial, and obviously she always has calcium available in her grit. I don't really want to take it away from her because... she's feeling so good she laid an egg for me today! She's gotta be in need of calcium due to that, so I'm a bit unsure.
But at the same time, she isn't one to gorge herself on grit, and the bacteria can't be causing her too much grief with her being already at normal weight, super energetic and pumping out eggs... So maybe it's not a big deal if she has a bit of calcium and the antibiotic isn't
quite as effective as usual?
I'm should be getting some other medications and supplies in the mail before long but I'm unsure exactly when they'll arrive. I guess I could wait and give her some of those instead but I'd really like to get all this behind us.
