My 2week old chicks

[pinkie]

We have put them in their coop that is inside a post and beam heavy duty quarter inch screening all the way around even the ground. They seen to love it out during the day and I have the lite on at nite I just noticed on 2 of the babies it looks like a mosquito bite on side if face the temp in the coop is 75 very roomy and the lite is off in the day time they have their feathers and are cleaning them selves pulling out some feathers my thought is their new ones are coming in my concern is bugs biting them as the lite is on at nite the temp during the day are in the 80s so not cold. Is this normal for them to have what looks like a bite only 2 I noticed with this thanks any info would be great they are golden comet

I would suspect that they are getting bit.
