Rosy Bourke chicks - dead in shell
by Dave Stewart
I have a pair of rosy bourkes who share an aviary with several pairs of zebra finches and a pair of chinese quails. The rosy bourkes have bred three times. Each time I get 5-6 eggs. The female sits fast on the eggs after the first few are laid, except for bathing early in the morning, and occasionally coming down for a drink of water. The Male feeds her in the nestbox.
Each time the eggs have passed the normal hatching time and when I investigate I find all the chicks dead in shell (not fully formed) My birds get a varied mix of seed, fresh fruit and vegetables, and crumbled brown bread on a daily basis. Where am I going wrong? I successfully breed budgies, cockatiels, kakarikis, finches and turquoisines under the same conditions and with the same feeding routine. Can anyone advise me?
