Hello I have 3 silkies and 1 EE chick that are going to be 4 weeks old on Sun. I have biult them an open air coop (It is very hot here in texas) until they are old enough to introduce them to the rest of the flock. I've noticed that mosquitoes are really bad right now and was wandering if i need to be concerned for the chicks. They have been outside since Sunday and seem to be o.k. Any suggestions? Am i worrying for nothing?
