Mercury spilled in … It happens sometimes. 0000009537 00000 n 0000036860 00000 n Hatching duck eggs requires a humidity level of 65% on average, or 85* to 88*F on a wet bulb thermometer. In most failed hatches, humidity has usually been too high, resulting in a small air sack and the duckling ‘drowns’ in the shell. 0000006982 00000 n the other egg did not show the late-time air sac increase and is still quite full of veins and liquid. %%EOF 0000005765 00000 n 0000016169 00000 n 0000030899 00000 n endstream endobj 86 0 obj<. 0000060874 00000 n 0000006708 00000 n 0000061507 00000 n It never ceases to amaze me how wonderful mother nature is and if you continue to have problems, maybe incubation using a broody hen would be the answer next year? 0000007119 00000 n 0000036589 00000 n 0000033929 00000 n There is movement in there, though. 0000010199 00000 n <]>> 0000021347 00000 n 0000004818 00000 n 0000003312 00000 n Is there any way to help it ‘dry out’ at this point? 0000059405 00000 n Eggs failing to hatch can be a disappointing and sometimes costly experience and finding the cause of the problem can and will help prevent future losses.

This seems to happen the most with chickens but it is not uncommon for this to occur with waterfowl too. Ducks that can’t make it out of the shell often grow slowly and are at greater risk for being trampled by larger siblings. Do not fumigate from 24 to 96 hours of incubation. I’ve got 2 duck eggs in lockdown (with 2 chickens -both of these are pipped). 0000060122 00000 n If you suspect the parent stock has been closely bred for a number of years, introducing some new blood should give you some better results. 0000060827 00000 n 0000060302 00000 n 99.5ºF (37.5ºC) will cause late hatch. ��z�p��g�Y5��"@O�A�,�F�*�&���޹��"Q��)��t�K����;6b�����Ql�Ǡ������3�����1�BnD�^U)�.��%n뭿 +=N!��{�zٜ1冥1@k��7��ޯԡ�%����f���$O>�ľu� ��~��l�4�(��ծD$ �2��t��?�����9}�ML-U�~Vdqf>�l��*Pv\���dFa��L���r��ZI�`�.� ����/����]���6a(q�,E�߭{3x����gW��X��g�3��ƨ���eH}�0��D�`�Z&ݰ�u��#B�$��}� j ��wp �~q*���eee���Lcx���G�n>[2uY|�K��QQ�q]D��Wc�� ���k�6�l� X�������=:���G�W�3���u� ͝�+M\J��M���&M|t��6��#'Y�:E2G�@z�bl�e��S�P�C_�n�dq�n�#���E�^F���ma�-i4��2������$;��P��`���.���цe!�~� 0000003653 00000 n He keeps Cream Legbar chickens, Silver Sebright bantams and hybrid layers for eggs, Abacot Ranger ducks, Brecon Buff geese and some quail. 0000060232 00000 n If you are buying hatching eggs, on Ebay for example, try to establish whether other people are successfully hatching eggs, (not just having fertile eggs) comments like “4 lovely ducklings, thank you!” are the comments you are hoping to see as well as pictures of ducklings the breeder has hatched themselves. 0000005355 00000 n 0000005491 00000 n 0000059351 00000 n 0000007258 00000 n 0000060417 00000 n 0000061731 00000 n 0000061083 00000 n 0000004546 00000 n If you refer to the incubation troubleshooting guide, there is just about everything listed from the wrong temperature, lack of turning, insufficient ventilation and even disease in the parent flock, however with a small amount of detective work, you can hopefully rule some of these possible problems out.

This seems to be a common problem that people have, even though they have a modern incubator, often with automatic temperature and humidity control.
