This will demonstrate the low blood calcium and in most cases a high blood phosphorous. In egg bound birds we need to solve the secondary problem of the stuck egg first. In these the egg needs to be removed manually, with or without anaesthesia. Once recovered, then we can deal with the calcium deficiency long term. The underlying cause is diet.
Seed is high in phosphorous and low in calcium.
What calcium is available is often poorly absorbed into the bird, due to the nature of the calcium and in some cases a combined vitamin D 3 deficiency as well. Some seeds are also high in fat, which may also reduce calcium uptake. This must be easily absorbed from the intestine and ideally also contain vitamin D 3 . Many supplements may be inadequate. We recommend ' Calcivet ' from the Birdcare Company.
