Hi, I've had a family of seagulls on my roof the last few weeks. The chick is just over 2 weeks old. The last couple of days, I've noticed the mother has been very quiet and not sitting on the telephone mast pole as I had been doing for a few days prior, staying on the roof instead. I noticed tonight that it's hopping on one leg, but it can still fly. Any advice to help the seagull? I'm giving it food and water.
