Tractor Supply fails again. The only way I could buy liquid calcium is as the Goats Prefer Calcium Drench. I have spent some time now trying to find dosing for liquid calcium, and just can't find it. I have a flock of 20 and they empty their 2 gallon waterer in just over a day. So whatever I put in the water would be a one day dose. I have separated on hen with moderately bad prolapse, and have discovered another who looks to have an irritated vent, but no prolapse yet. I am treating the wounds the best I can and feel good about what I am doing, but I need dosage for the calcium, to help prevent further prolapse among my hens. How much calcium should a hen get each day?
