I have two chickens who are 10 weeks old. One is a brown leghorn and the other chicken is a barred rock. I've had them for about 2 weeks now. In the past few days, I have noticed an amount of feathers being lost. I notice they probably have lost about 10-20 feathers a day the past 2-3 days, some large feathers and some small fluffy feathers. I haven't noticed any itching or biting type behaviors and they are eating and drinking what seems to be normal amounts. Is this a lot of feathers for them to lose?
I have some 10 week old chicks as well, they are loosing some feathers but not too much. Your chicks are are probably molting as well, here are some links that will help: https://www.backyardchickens.com/a/chickens-loosing-feathers-managing-your-flocks-molt https://www.backyardchickens.com/t/699302/when-do-chickens-moult
