We have 2 groups of layers, a group of 44 and a group of 165 approximately. The laying has been well till the beginning of January and then it went down in the 2 groups, most likely because it is hot (We are at the coast). Since mid february it was still going down in the big group, but now the last week we have only around 100 to 110 eggs of the big group, while from the others we have around 37 eggs. We have no idea what is wrong with the big group. Also the size of the eggs is smaller. They are younger then the other group, but it is like they just start to lay. Does somebody has any idea what the problem can be ? Thanks
