Hey, all... Here's the rub... I have been raising 2 Silkies since birth. They are almost 4 weeks old. I had them in a 20 gallon long aquarium with a heat lamp. They have been doing fine and spending extensive time outside(5+ hours) for the past week or so. Here's my worry... I have transfered the birds from the aquarium to a 3x3 plastic pen and moved all their amenities with them. Water, food, lamp etc. Since moving them over they have been CHIRPING non stop. LOUD! Should I be concerned? Thanks for any and all replies. ..
