Went out to feed chickens and rooster seemed ill. he has been lying down all day and does not want to get up. went to pick him up and his crop is HUGE it feels like it is full of air. Tipped him on his side to check him out and water came out of his beak so I tipped him forward and ALOT of water has come out of his beak now. I am new to chickens so i have no idea what could be wrong. he is only 11-12 weeks old???? i think. Please Help!!
