I am running a logistic generalized linear model using R that measures habitat selection of a hatchling animal. I used a random paired design, therefore every time a hatchling was located I measured a suite of variables at its location as well as a random location nearby. Locations the hatchlings were found at received a 1 and the random controls received a 0.

I suppose I counted every record of a hatchling as independent. Is this wrong going by the comment I received back? I sampled 66 individuals which resulted in some 700 locations. I read up on fixed and random effects to understand his comment. My habitat measurements are fixed variables, but I assume he is worried that individual is a random effect not being accounted for? Is there a sort of test for this? Thanks for any help everyone!!
