I have 5 4wk old chicks. Last night they went to bed as little angels. This morning, from the beginning, they've been acting crazy! The more dominant one was especially bossy. Didn't allow the others to say hello like they normally do. Pecked at several of them as they approached food and water. The lowest one on the totem pole, which normally ignores everything, is chasing others, and well...acting bossy too. The remaining ones are also acting out of character and playing a bit rough. No one is hurt, but, my goodness...what's going on? Do they start acting up when they are feathering- in? 1-I believe that they have plenty of living space as there are only 5 in an extra large whirlpool tub. Plus they are still quite small. 2-I monitor the temp several times a day. When it gets warmer than 80 degrees, if it's warm outside with no cool breezes, I take them outside for some R & R 3-They have clean food/water bowls...almost all the time :0) Please help. I've had horses, cats, dogs, parrots...Just want to make sure it's normal.
