Yes, but it may never lie down. Lops must have their ears placed in a very particular spot on their heads to have a proper lop look. The term used when ears are not in the right spot is 'slipped crown' and usually the ears are too far back on the head to lie straight down.
Also, sometimes they can be too tight/pinched in the crown. My Mini Lops Lop no later than 4-6 weeks. At 8 weeks, your French will probably have that permanently. A good crown, is when you can put 3 fingers across the top without them slipping backward (slipped crown). You want them to be relaxed and rest right behind the eye. Pictures are also helpful
