When I let my chickens out this morning my rooster came out belly crawling, he is only 4 months old, he is a lemon pekin, I picked him up and brought him inside, after about 10 mins he was upright walking, so I went to put him back out, and he panicked and flew then fell to the floor, then he belly crawled again, I again brought him inside and after 10 mins he was walking again, I have now put him out and he is walking around normally and doing his rooster job, should I be worried????
