Hi there Bee, How are you doing? As you can see, I am catching up! I get busy and the world passes me by! Let's see, a BA is a black Australorp, a BO an orpington, and I think I know the others, but what's a WR? My Americaunas don't eat so much but give me an egg every day except in the middle of winter. Are they considered non thrifty because they aren't a meat bird? And about my chick with the sour crop....I went to my feed store and showed her to the guys there who said don't do anything, just watch to see if it wouldn't right itself since she was fine in every other way. So I spent the better part of a day researching the malady and found that the general concensus is to medicate them with Monistat suppositories for female yeast infections. Isn't that a hoot? So I went to the pharmacy armed with the name of the same ingredient but for poultry. We found it in all the treatments for jock itch and athletes foot. So instead of paying 15-22 dollars for Monistat, I paid $5 for a foot spray. She gave me some small syringes and I gave the chick a dose of the stuff. I lay in bed realizing I had given it a bunch of propelant that may have been tolulene or such other carcenagin. I wondered if I'd find a dead chick when I went to check this morning. She was fine, crop smaller. Next dose I let it aireate (sp) for the propellant to evaporate and added water and yogurt. They also used the cream which was also for itch and had a lot of other ingredients so didn't go for it. Lots of reports of success, but a vet said the yeast infection was a result of something else wrong like impaction, etc. We'll see what happens. Her crop is so large after a day of eating it is practically dragging on the ground. : )
