Please help, We have two 7 month old ISA brown hens and have had them since they were day old chicks. They are extremely well cared for, on premium layers pellets and a much loved part of our family. Our bigger and stronger black hen olly has been hit and miss with her laying for the last week and I have been finding her nest box wood shavings wet in the mornings. This afternoon while free ranging her behaviour became off and she was quite subdued. She then started dripping clear liquid from her vent. This happened for a few minutes before she squatted and laid two shell-less eggs. One was just the yolk with no membrane at all and the other which followed within a second was a 'rubber' egg! Her dripping of clear fluid continued for another few minutes. Any advice/tips on what's going on with my girl would be greatly appreciated!! Thanks guys!!!
