For my chicken that has cystic oviduct, should I give calcium and D daily or just for a week and see how she does?You can use 300mg of the calcium citrate. If you have 600 mg of calcium that is okay to use as well. There was some discussion her recently because many thought that 600 mg was the dosage, but some found out that the tablets may only have 300 mg. I think Azygous realized that was enough. The calcium I have is 600 mg per tablet, but it is not citrate.
